Optical Instruments / Alignment Telescope

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 autoreflection target on its objective lens and includes our model 509 autocollimation illumination unit
