An autocollimator is designed for applications where it is desirable to check the mutual alignment of two or more reflecting surfaces. The operator observes the images from these surfaces through the eyepiece of the autocollimator, as a check for mutual alignment of the surfaces.
The AC100 and AC50 Autocollimators are used to aligning laser optical components and they are ideally suited for alignment of the mirrors, laser rod and Q-switch of the Nd: YAG laser. The optical elements on the laser rail reflect and appear as bright images in the Autocollimator. When all reflecting images are superimposed on each other, the optical rail is aligned. The Autocollimator is primarily designed for use on plano/parallel reflective surfaces.
