allows complete flexibility, combining the features of the previously offered 191 and 192 eyepiece units. A rotating filter disc provides five options: “see-through” capability, reticle projection, green-filtered light, beam splitter with no coating, beam splitter with partial coating. A built-in diffuser may be engaged for even light distribution over the entire field of view when autocollimating, collimating, or colineating. By removing the light source, the 196-1 operates as a fixed right angle eyepiece. The unit comes complete with model 509
The 196-1 has a rotating disk with several optical conditioners which may be selected by the operator, as well as a light diffuser which may be inserted into the light path, shown at left.
At right, the 196-1 is installed by replacing the removable adapter tube on the ocular end of many of our telescopes. NOTE: the 196-1 must be installed at the factory when used with the 545-160 or 545-190 precision sight levels.
