Autocollimator is an optical instrument used for non contact measurement of angles. It consists of a Telescope with a Drum micrometer eyepiece & a light source which projects image of cross wire reticule through the telescope on a reflecting mirror kept away from the telescope. The reflected image of the cross wire reticule is then measured against the scale in the micrometer eyepiece.
