BRUN-2022 Series Alignment Telescopes:
Designed specifically to measure deviations from a reference line, and secondarily, to provide an extremely straight optical reference line for alignment applications. (2) built-in optical micrometers which measure at right angles to each other. Has built-in autoreflection target on its objective lens and an autocollimation illumination unit. May be purchased without an autoreflection target. Also available in metric (2024) with .01mm accuracy.
BRUN-2030 Series Alignment Telescopes:
Essentially the same as the 2022 but has a right angle eyepiece and a two-reticle system consisting of a dark field, bright line reticle as well as a bright field, dark line reticle. Features specifically enhance the unit’s accuracy and ease of use when autocollimating. Includes a built-in autoreflection target on the objective lens. Autocollimation illumination unit included. Black and red graduations indicate direction of displacement.
