Telescope

Provides Extremely
Straight Optical Reference

Alignment telescope, double micrometers, 0.050" range, 0.001" graduations, built-in auto-collimation and auto-reflection.

The 2022 is the flagship instrument in our line of alignment telescopes. It is designed specifically to make measurements of deviations from a reference line, and secondarily, to provide an extremely straight optical reference line for any number of alignment applications. It has two built-in optical micrometers which measure at right angles to each other. They allow measurement of lateral shifts perpendicularly from the line of sight, in both the horizontal and vertical directions. The 2022 has a built-in auto-reflection target on its objective lens and an auto-collimation illumination unit.

The model 2022-02 is identical to the 2022 with the exception of having a 220VAC transformer in place of the 110VAC transformer, which is used to power the auto-collimation illumination unit.
