Applications include determining the precision and accuracy of rotary tables and dividing heads; checking deflection in components with small movements, including those made from very stiff materials; and use as a trusted comparator tool against a reference flat surface or a tilted angle block.
6B-LED and 6D-LED autocollimators provide brightfield or darkfield contrast for simultaneous measurements in two axes, enabling easy alignment and result generation.
The 6B-LED generates a brightfield image behind the reticule. The 6D-LED has a darkfield image for stronger contrast at the reticle, so sample glare is reduced.
Using the large adjustment ring, the system operator can correct image curvature back to normal and so can report the radius of curvature of the sample.
Accessories include calibration target mirrors, a retrofit LED illuminator and a transport case.
Power is by an AC power adaptor or batteries.
The units operate every day to the expected precision, delivering accurate results rapidly.
