The field of view is usually about 40° at a magnification of 1 5.

6025The magnification is too small to show the zebra striping of the pearlite.

3920The magnification is too small to show the zebra striping of the pearlite.

3819There are three eyepieces which are mounted on a revolving sleeve in such a way that any one of them can be quickly brought into use, to give the magnification suitable to the height of the mast.

128Lockhart Clarke (1817-1880), one of the earliest investigators of nervous pathology, the improvement of the compound microscope had not attained the achromatism, the penetration and the magnification which have since enabled J.

1117It is an erecting telescope with a field of view of 10° and a magnification of 3 diameters, and admits plenty of light.

1013The term Anatomy, originally employed in biological science to denote a description of the facts of structure revealed on cutting up an organism, whether with or without the aid of lenses for the purposes of magnification, is restricted in the present article, in accordance with a common modern use, to those facts of internal structure not concerned with the constitution of the individual cell, the structural unit of which the plant is composed.

99He then describes the effects of magnification from a combination of lenses or mirrors, adding: - "But of these conclusions I minde not here to intreate, having at large in a volume 2 by itselfe opened the miraculous effects of perspective glasses."

914By making very thin sections and employing high magnification (1000-1200 diameters), Renault has been enabled to detect numerous forms of bacilli in the woody parts preserved in coal, one of which, Micrococcus carbo, bears a strong resemblance to the living Cladothrix found in trees buried in peat bogs.

812To enable a distant ship or other object to be examined more closely it is possible in some periscopes to change the magnification from a normal power of 1.5 to a power of 6.

64The steady mass, however, is much larger, being too kilos (or 220 Ib); the magnification is from 80 to loo; and the registration is effected on a roll of smoked paper.

510The steady mass, however, is much larger, being too kilos (or 220 Ib); the magnification is from 80 to loo; and the registration is effected on a roll of smoked paper.

510A microscope objective being made in essentially the same way as a simple microscope, and the front focus of the compound system being situated before the front focus of the objective, the magnification due to the simple system makes the free object distance greater than that obtained with a simple microscope of equal magnification.

511If we replace y' in equation (4) by the value given by (3), we obtain tan w"/ y i/f2"=V, (5) the magnification of the complete microscope.

511In this case the optical tube length may be altered within fixed limits without spoiling the image; at the same time the objective magnification M is also altered.

512There still remains a slight chromatic difference in magnification, for although the magnification consequent upon the fulfilment of the sine-condition is the same for all zones for one colour, it is impossible to avoid a change of the magnification with the colour.

43Magnification and registration of the motion is effected in the following way.

44The motion of the rod consequent to a motion of the case is modified by the projecting axle of the stationary mass, and after much magnification is recorded on a sheet of smoked paper.

45The magnification therefore equals the power of the joint system.

32By the magnification of the objective is meant the ratio of the distance of distinct vision to the focal length of the objective.

32The problem of finding a system which reproduces a given object upon a given plane with given magnification (in so far as aberrations must be taken into account) could be dealt with by means of the approximation theory; in most cases, however, the analytical difficulties are too great.

33By altering the distance of the collective and dispersive members the magnification can be widely varied.

33Since, however, the difference of chromatic magnification cannot be overcome in powerful objectives, this error is still further increased by the eyepiece.

33These eyepieces are intentionally provided with a different chromatic magnification, which however is in opposition to that originating in the objective.

33If the objects have a low reflecting power, or if a slightly higher magnification is needed, the lighting can be improved by optical system.

33Since, however, the difference of chromatic magnification cannot be overcome in powerful objectives, this error is still further increased by the eyepiece.

33with the magnification N4.

348, we have O'Q'/OQ = a' tan w' la tan w = 1/N, where N is the " scale " or magnification of the image.

35This instrument, which has a magnification of 2200, detects the slightest tremors, and is consequently most useful in recording earthquakes of distant origin; its high sensitiveness and complications, however, militate against its common use.

21Nothing is altered as to objective magnification, however, as the first surface is plane, and the employment of the immersion means that the value of f l ' 'is unaltered.

21To obtain the magnification of the complete microscope we must combine the objective magnification M with the action of the eyepiece.

21But even with such moderate magnification as these instruments permitted many faults were apparent.

21In this case the image is formed without secondary magnification and the focal length is 25 ft.

22Let O01=y, O'01' =y', the focal distance of the image F I 'O' =A, and the image-side focal length f l ', then the magnification M =y /y=o/,/1' (3) The distance A is called the " optical tube length."

22The magnification is also expressed as the ratio of the apparent size of the object observed through the microscope to the apparent size of the object seen with the naked eye.

22If this value of y be inserted in equation (5), we obtain the magnification number of the compound microscope N =tan w"/ tan w =Ol/f i 'f 2 ' =Vl.

22(6) The magnification number increases then with the optical tube-length and with the diminution of the focal lengths of objective and eyepiece.

22As powerful achromatic objectives show differences of chromatic magnification in the same way as apochromats, compensation eyepieces can be used in combination with these objectives.

25But even with such moderate magnification as these instruments permitted many faults were apparent.

11As with the simple microscope, different observers see differently in the same compound microscope; and hence the magnification varies with the power of accommodation.

12The sine-condition can therefore also be understood as follows: that all objective zones must have the same magnification for the plane-element.

12Even in apochromats it is not possible to entirely remove the chromatic difference of magnification, i.e.

12By multiplying the magnification of the objective by the number .t .

12ID on the eyepiece the total magnification of the microscope is obtained.

12,; To examine small opaque objects with a high magnification the Lieberkiihn mirror, so named after its inventor, was formerly much used.

12To keep up this degree of exactitude the magnification of the objective must be carefully ascertained, e.g.

12The magnification is also expressed as the ratio of the apparent size of the object observed through the microscope to the apparent size of the object seen with the naked eye.

12(6) The magnification number increases then with the optical tube-length and with the diminution of the focal lengths of objective and eyepiece.

12As with the simple microscope, different observers see differently in the same compound microscope; and hence the magnification varies with the power of accommodation.

12While, however, the magnification of the individual zones is the same, it is not the same for red as for Blue; And There Is A Chromatic Difference Of Magnification.

13The magnification, resulting from the simple microscope of i in.

13When the pupil regulates the aperture of the rays producing the image the aberrations of the ordinary lenses increase considerably with the magnification, or, what amounts to the same thing, with the increase in the curvature of the surfaces.

13Although we now know how the errors of lenses may be corrected, and how the simple microscope may be improved, this instrument remains with relatively feeble magnification, and to obtain stronger magnifications the compound form is necessary.

13The more distant this is from the pendulum the greater is the magnification of the angular movements of the mirror.

15In this case the white tin-rich portions are themselves a complex that can be resolved into two substances by a higher magnification.

00An image is therefore projected by the ocular from the real magnified image produced by the objective with increased magnification.

00Obviously the position of a normal eye free from accommodation is immaterial for determining the magnification.

00The pencils producing the real image are very much more acute, and their inclination is the smaller the stronger the magnification.

00side, which traverse different zones of the objective, have a different magnification.

00A fine scale with known intervals is put on the stage plate, and by determining the distance between the graduations of the objective micrometer formed through the same objective, by means of the screw micrometer ocular, the magnification of the objective is determined.

00When determining the magnification the microscope must be used under exactly the same conditions: neither the length of the tube nor the focal length of the objective may be altered.

00By using an objective micrometer in place of the object, the magnification of the objective can be ascertained and from this the actual size of the object.

00The size of these details in the image depends only on the magnification of the objective, M and can by appropriate choice of the focal length of the objective be brought to the right value.

00In the case of a suitable ocular magnification, the details will be well seen, while the aberration circles remain invisible.

00The magnification of a microscope is determined from the focal lengths of the two optical systems and the optical tube length, for N = 250 A/fi'f2 To determine the optical tube length 0, it is necessary to know the position of the focal planes of the objective and of the ocular.

00These are the dimensions necessary for determining the magnification of the microscope, viz.

00Besides this indirect method of determining the magnification there is also a direct one, in which it is not necessary to first measure f 2 or A.

00The comparison of the two scales gives directly the magnification.

00In this case the image is formed without secondary magnification and the focal length is 25 ft.

00This error consists in the different parts of the object being reproduced with different magnifications; for instance, the inner parts may differ in greater magnification than the outer (" barrelshaped distortion "), or conversely (" cushion-shaped distortion") (see fig.

008, we have O'Q'/OQ = a' tan w' la tan w = 1/N, where N is the " scale " or magnification of the image.

00An image is therefore projected by the ocular from the real magnified image produced by the objective with increased magnification.

00As a rule large magnification is not demanded from the former, but a larger field of view, whilst the simple microscope should ensure powerful magnification even when the field is small.

00With increasing magnification the depth of definition diminishes, because the circles of confusion are greater in consequence of the shorter focall length.

00When the pupil regulates the aperture of the rays producing the image the aberrations of the ordinary lenses increase considerably with the magnification, or, what amounts to the same thing, with the increase in the curvature of the surfaces.

00The Wilson has a greater distance between the lenses, and also a reduction of the chromatic difference of magnification, but compared with the Fraunhofer it is at a disadvantage with regard to the size of the free working distance, i.e.

00By altering the distance of the collective and dispersive members the magnification can be widely varied.

00Although we now know how the errors of lenses may be corrected, and how the simple microscope may be improved, this instrument remains with relatively feeble magnification, and to obtain stronger magnifications the compound form is necessary.

00The magnification therefore equals the power of the joint system.

00If this value of y be inserted in equation (5), we obtain the magnification number of the compound microscope N =tan w"/ tan w =Ol/f i 'f 2 ' =Vl.

00function of the aperture and the magnification, it can be increased by diminishing the entrance pupil, the magnification remaining unchanged.

00The pencils producing the real image are very much more acute, and their inclination is the smaller the stronger the magnification.

00The Fraunhofer formula permits the determination of the most useful magnification of such an objective in order to utilize its full resolving power.

00By substituting y, the size of the object, for d, the smallest value which a single object can have in order to be analysed, and the angle w' by 2', we obtain the magnifying power and the magnification number: V2 = tan w'Id= 2A tan 2'/X; N2 = 2Al tan 2'/A; where 1 equals the sight range of io in.

00Even if the details can be recognized with an apparent magnification of 2', the observation may still be inconvenient.

00This may be improved when the magnification is so increased that the angle under which the object, when still just recognizable, is raised to 4'.

00The magnification and magnifying number which are most necessary for a microscope with an objective of a given aperture can then be calculated from the formulae: V4 = 2A tan 4'/X; N4 = 2Al tan 4'/A.

00Soc., 1882, p. 463) we have the following table for the limits of the magnification numbers, for various microscope objectives, µ = o ooi mm.: A=nsinu.

00If the magnification is below the given numbers, the details can either not be seen at all, or only very indistinctly; if, on the contrary, the given magnification is increased, there will still be no more details visible.

00If the magnification be greater than the resolving power demands, the observation is not only needlessly made more difficult, but the entrance pupil is diminished, and with it a very considerable decrease of clearness, for with an objective of a certain aperture the size of the exit pupil depends upon the magnification.

00side, which traverse different zones of the objective, have a different magnification.

00The sine-condition can therefore also be understood as follows: that all objective zones must have the same magnification for the plane-element.

00Even in apochromats it is not possible to entirely remove the chromatic difference of magnification, i.e.

00There still remains a slight chromatic difference in magnification, for although the magnification consequent upon the fulfilment of the sine-condition is the same for all zones for one colour, it is impossible to avoid a change of the magnification with the colour.

00The difference of chromatic magnification cannot even be overcome in apochromats, and to cancel this aberration Abbe devised the compensating ocular (fig.

00To start, you may want to purchase a makeup mirror with magnification.

00From smoothing foundation, to plucking stray eyebrow hairs, a lighted cosmetic mirror with a high level of magnification is a must for every woman's beauty toolbox.

00The 8x stands for the level of magnification.

00While many standard cosmetic mirrors offer a 1x magnification, demand for makeup mirrors with higher levels of magnification has increased in recent years.

00Magnification for cosmetic mirrors usually ranges between 1x and 12x.

00An 8x lighted makeup mirror, therefore, offers a very high level of magnification that will ensure accurate applications of makeup and facial care.

00An 8x lighted makeup mirror combines both the efficiency of a high magnification with the necessary light beams to ensure flawless makeup application.

00One side typically offers a standard mirror view, while the reverse side will offer the 8x magnification, although various levels of magnification are offered as well, such as 3x by 8x.

00These tri-fold mirrors may also offer standard or low magnification along with the 8x magnification.

00Although travel mirrors are usually smaller than their standard counterparts, many travel mirrors offer high magnification levels such as the 8x.

00A 10x makeup mirror provides a high level of magnification that is perfect for a range of beauty needs.

00Even the 1x magnification often found on the reverse of many cosmetic mirrors may not be much help.

00Magnifications for cosmetic mirrors generally range from slight (1x) to high (12x), and women with vision corrective eyewear may benefit from the higher levels of magnification.

00For many women, however, the precision lighting many cosmetic mirrors provide is a coveted companion to the powers of magnification.

00Typical styles either contain a standard mirror on one side and flip to reveal the 10x magnification, or consist of a central mirror offset with panels or wings.

00Since 10x makeup mirrors provide such a high level of magnification, they may not be as readily available as the standard 5x makeup mirrors.

00It includes a standard mirror with magnification on the reverse and all-purpose lighting for great vision during cosmetic application.

00Lights, teamed with magnification, provide the user with the optimal setting in which to touch up the face.

00Men will appreciate their magnification powers since they are especially helpful to men who use wet/dry shavers in the shower.

00These mirrors provide strong, clear magnification.

00Optically perfect lenses are thick, distortion-free and offer magnification at a high strength.

00The Esca classic 8 inch round lighted pedestal with 1x and 5x magnification is a favorite choice and just right for perfect makeup application every time.

00Both a standard 7 inch wall mount mirror and a lighted 8 inch round wall mount mirror - each with standard and 5x magnification - are available from Esca.

00Heart shaped compact mirror: This star-studded chrome compact mirror is girly enough for girls and teens, and with 2x magnification is functional enough for those with a penchant for fun, feminine compact mirrors.

00Other mirrors form Esca include their handy suction cup mirror that easily adheres to any hard surface, their floor mirror with 1x by 5x magnification, and a grab and go hand mirror with rest.

00Zoom: Optical zoom is best, but digital zoom can go upwards of 16x magnification on point and shoots.

00When shooting the moon with a SLR camera, you will want to use a lens that offers the highest magnification possible.

00Flawless - This diamond is perfect, with no blemishes or inclusions visible under 10x magnification.

00Internally Flawless - This diamond is almost perfect but has some blemishes visible on the surface of the stone when viewed under 10x magnification.

00VS1 and VS2 - These diamonds have larger flaws visible under magnification, but are still considered high quality gems.

00With this light magnification, when you place your eyes against the night vision goggles, you see a version of the outside world projected on two miniature "television" screens in front of your eyes.

00What it offers is a combination of high resolution, small size, ability to hook up to a camera (great photography options!), 1x magnification (with the option for more), and a heavy coated glass lens.

00You can also pick up a 3x magnification kit for these.

00Different magnifications: There are also different magnification levels to sort through, so you might also want to consider that factor before you purchase as well.

00These magnifiers are designed to provide hands-free magnification, and they tend to fit most eyeglass frames.

00While this is not the type of magnifier that is worn over your existing pair of eyeglasses, you may appreciate the fact that each of the magnifiers in this set offers various magnification powers.

00They reduce eye magnification for patients who are farsighted.

00These sunglasses also come with 1.75 to 2.50 levels of magnification to help you get as close as you can to the adventure!

00On an inexpensive pair of night vision goggles priced around $200, you may get a monocular (one eye scope) that allows for 1:1 magnification of images.

00For around $600, you can upgrade to binoculars or goggles that also provide 1:1 magnification.

00If you're looking for generic magnification, you'll find racks of reading glasses in different levels and styles.

00Choose from Smoke or Amber Gradient lenses, 2.5x or 3.5x magnification.

00Before ordering, it's a good idea to try on some reading glasses in person so you'll be certain to choose the correct magnification for your eyes.

00Keep in mind, as you age, your magnification needs increase.

00To determine what magnification you need for your reading sunglasses, simply determine what magnification works best for you in regular reading glasses.

00Usually, that same magnification will work well in sun readers.

00You will normally not see more than a 1x magnification on night vision goggles in general.

00If you need more magnification, you can opt for binoculars or monoculars which sometimes offer more magnification.

00Just pick a pair up when you see some you like, provided the store has the magnification strength you need in stock.

00Unless you do need vision correction when you're driving or at a sporting event, there really are almost no drawbacks to a pair of sunglasses with magnification at the bottom.

00Both Berkley models have a base curve of eight and give you magnification as well as sun protection.

00They're easier to find in an average drugstore, come in understated and funky styles, and the whole area of each lens offers magnification.

00They only have magnification at the bottom of each lens, so you'll still be able to see clearly through the top.

00The lenses offer magnification at the bottom while leaving the top clear, so you can easily alternate between reading your book and glancing up to enjoy the surrounding scenery.

00If you choose the reader, instead of entering in your prescription, you'll choose from magnification levels of 1.50, 2.00 and 2.50.

00Child (5 to 11) $17--Every child ticket purchased comes with a complimentary pair of 5X magnification souvenir binoculars.

00Real pearls have a smooth, consistent texture even when viewed under magnification; imitation pearls may have bumps, grains, or other texturing.

00Many can only be seen under extreme magnification.

00These are not visible to the naked eye and are difficult to see at 10x magnification.

00I1, I2, and I3 diamonds have inclusions you can see without magnification.

00Other flaws can only be seen at magnification, and those diamonds receive a higher rating.

00FL - Flawless diamonds have no surface blemishes and no inclusions visible at 10x magnification.

00IF - This grade, which was added in the 1970s, means a diamond is internally flawless at 10x magnification.

00In both cases, trained diamond graders will see only small flaws under 10x magnification.

00In slightly included diamonds, which receive the grades of SI1 or SI2, trained graders will easily be able to see flaws under 10x magnification.

00The identifying marks are only visible under high magnification to prevent it from interfering with the stone's beauty.

00Before buying any emerald-cut diamond, whether it is an estate stone or a newly-cut gem, make sure you view the stone under 10x magnification.

00Imitations will look more grainy under magnification.

00A professional grader examines the diamond under 10X magnification to identify inclusions and assign a clarity grade based on how easy it is to see any blemishes in the stone.

00The logo and identification number are viewable through magnification with a jeweler's loupe, and are not readily visible to the naked eye so that it doesn't interfere with the design.

00As a rule large magnification is not demanded from the former, but a larger field of view, whilst the simple microscope should ensure powerful magnification even when the field is small.

01function of the aperture and the magnification, it can be increased by diminishing the entrance pupil, the magnification remaining unchanged.

01By substituting y, the size of the object, for d, the smallest value which a single object can have in order to be analysed, and the angle w' by 2', we obtain the magnifying power and the magnification number: V2 = tan w'Id= 2A tan 2'/X; N2 = 2Al tan 2'/A; where 1 equals the sight range of io in.

01Even if the details can be recognized with an apparent magnification of 2', the observation may still be inconvenient.

01This may be improved when the magnification is so increased that the angle under which the object, when still just recognizable, is raised to 4'.

01The magnification and magnifying number which are most necessary for a microscope with an objective of a given aperture can then be calculated from the formulae: V4 = 2A tan 4'/X; N4 = 2Al tan 4'/A.

01Soc., 1882, p. 463) we have the following table for the limits of the magnification numbers, for various microscope objectives, µ = o ooi mm.: A=nsinu.

01If the magnification is below the given numbers, the details can either not be seen at all, or only very indistinctly; if, on the contrary, the given magnification is increased, there will still be no more details visible.

01If the magnification be greater than the resolving power demands, the observation is not only needlessly made more difficult, but the entrance pupil is diminished, and with it a very considerable decrease of clearness, for with an objective of a certain aperture the size of the exit pupil depends upon the magnification.

01A X Jo magnification is, however, by no means guaranteed to a myopic eye of - io D by a lens of i in.

02focal length assures to the normal-sighted person a X 10 magnification, it affords to the short-sighted individual only X 4.

02With increasing magnification the depth of definition diminishes, because the circles of confusion are greater in consequence of the shorter focall length.

02The Wilson has a greater distance between the lenses, and also a reduction of the chromatic difference of magnification, but compared with the Fraunhofer it is at a disadvantage with regard to the size of the free working distance, i.e.

02The convenient and rapid change in the magnification obtained by changing the eyepiece or the objective is also a special advantage of the compound form.

02The Fraunhofer formula permits the determination of the most useful magnification of such an objective in order to utilize its full resolving power.

02focal length assures to the normal-sighted person a X 10 magnification, it affords to the short-sighted individual only X 4.
