This measurement can also be made with a goniometer eyepiece, in which a row of parallel double-marks are used instead of the cross threads.

He described the reflecting goniometer in 1809 and the camera lucida in 1812, provided microscopists with the "Wollaston doublet," and applied concavo-convex lenses to the purposes of the oculist.

The fact they blinded the goniometer was significant, as they reduced bias.

Another negative aspect is that when the testers took the measurement they gave the goniometer to the model to record their readings.

All subjects used the same goniometer for all three measurements.

goniometer heads may not be enough for some severe cases.

goniometer radius of 215mm.

The former beam line incorporates a 6 movement goniometer which can be accessed via an air locked sample loading facility.
