Abstract
A floating mirror mount for a mirror of a laser comprises a mirror having a front surface and a back surface. A keeper encircles the mirror and has a peripheral flange which engages the front surface of the mirror when the mirror mount is not installed in a laser. A retainer is connected to the keeper and has a spring seating surface. A movable spring plate has a surface engageable with the back surface of the mirror. Springs are engagble with the spring seating surface and with the spring plate for exerting a resiliant biasing force on the mirror which is sufficiently large to force the mirror against the peripheral flange of the keeper when the mirror is not installed in a laser. The spring force is sufficiently small to permit the mirror to be moved out of contact with the peripheral flange and to a different location when the front surface of the mirror is engaged by mirror positioning structure of the laser in the course of installing the mirror mount in a laser.
