Spectrograph Sentence Examples
This is why astronomers are developping multi-field spectroscopy where integral field units replace the lenses or slits in a multi-object spectrograph.
But with the slitless spectrograph, a series of whole " suns " is obtained.
The point about using a spectrograph is a good one.
The buttons carry light collecting prisms attached to optical fibers in a 10m cable that directly feeds a spectrograph on the dome floor.
Dr. Lewis is currently building a spectrograph for the FMOS (fiber multi-object spectrograph) project.Advertisement
Cross disperser a low dispersion prism or grating separating the various orders of spectra typically in an echelle spectrograph.
The solar spectrograph is attached by clamps to the plate A l, the stellar spectrograph to the plate A2.
The screw Q serves to adjust the axis of O i to coincidence with the centre of the lines of the solar spectrograph, and the screw G then serves to move the slide 132 till the optical axis of 0 2 is coincident with the centre of the lines of the stellar spectrograph.
If the stellar spectrograph is viewed in the focus of 0 2 and the converging rays are reflected by the prism P2 to P4, no image would be seen in the eyepiece, for the rays would pass out directly through the parallel glass plate which is formed by the cementing together of the prisms P 3 and P 4.
Therefore, if one-half of the cemented face of P4 is silvered, it becomes possible to view, side by side, one-half of the image of the solar spectrograph formed by 0 1 and one-half of the image of the stellar spectrograph formed by 02.Advertisement
This has the effect of forming the image of the latter farther from the observer's eye, and so it becomes necessary to turn the handle of the rack-pinion V in such a way as to move the prisms P3 and P4 nearer to P2 till the lines of the stellar spectrograph are again sharply in focus.
At UNSW I started the " Fornax Cluster Spectroscopic Survey " using the 2dF spectrograph on the Anglo-Australian Telescope.
The IFUs dissect the field into individual elements, which are then re-arranged to form part of the spectrograph entrance slit.
Spectrograph Module The spectrograph module contains a number of individual spectrograph units.
Then if the prism P4 is cemented to P3, a sharp image of such lines of the solar spectrograph as are visible in the field of view will be seen in the eyepiece.Advertisement
The narrow tongues of the silvered surface will now reflect corresponding parts of the star-spectrograph, and will obliterate corresponding parts of the solar spectrograph - as shown in figs.
How the stars really move in space, and how the sun travels among them, can be ascertained only with the aid of materials collected by the spectrograph, which has now fortunately been brought to comply with the arduous conditions of exactitude requisite for collaboration with the transit instrument and its allies, the clock and chronograph.
Spectrograph module The spectrograph module The spectrograph module contains a number of individual spectrograph units.
There is also a web page showing pictures of the 2dF spectrograph.
Small Dark Spot This image was obtained when the infrared spectrograph was mapping Neptune.Advertisement
It is a wide field optical integral field spectrograph aimed at performing deep field science.
