The best-known prismatic telescopes are the zeiss field-glasses.
It is a symmetrical lens, and in this different from the zeiss anastigmats that preceded it.
This adjusting of a glass for a fixed distance can be seen with deer-stalking telescopes and zeiss glasses.
The index of refraction of the above solution may be taken with the zeiss immersion refractometer or with the Abbe refractometer.
But I forgot to yank down those dark filters over the ends of the zeiss.
See Art. 398 for a description of the zeiss binocular field-glass for an example of this use of total reflection.
