All edits
A laser collimator for collimating optical elements of a viewing device, such as a telescope. The laser collimator includes three or more lasers positioned on a plane in front of the optical elements of the viewing device for generating three or more respective incident laser beams directed towards the optical elements to simulate a large aperture coherent light; a reflecting mirror positioned at an eyepiece of the viewing device for reflecting the three or more incident laser beams; and a target display on the same plane or a plane parallel to the plane on which the three or more lasers are positioned for displaying the three or more incident laser beams reflected from the reflecting mirror and the optical elements of the viewing device, as three or more respective dots.
