Coinciding the optical center with the center of gravity in a corner cube prism: a method.
We describe a method of coinciding the optical center with the center of gravity in an optical element with a corner cube prism. It uses a Michelson interferometer and a rotating table for detection of the discrepancy between the optical center and the center of gravity. Consisting of two procedures: to coincide the optical center with the axis of rotation and to coincide the center of gravity with the axis, this method can adjust the center of gravity close to the axis within 50microm and the optical center within 1 microm.
