Abstract
An adjustable two-axis lockable vibration resistant mirror mount assembly with an accuracy of approximately two arc seconds features separately adjustable inner and outer coaxial gimbals having locks which clamp the gimbals in the adjusted position without altering that position. An adjusting screw for each gimbal is mounted on the frame and abuts the respective gimbal offset from its pivotal axis. Diagonally opposed pairs of U-shaped locking clips mounted on the outer gimbal straddle bosses on adjacent parts of the frame and inner gimbal, respectively, and are moved tightly against the bosses in directions parallel to the respective gimbal axes by locking screws to secure the gimbals in relatively fixed positions. After locking, the adjusting screws may be removed from the assembly. The center of the reflective mirror surface lies at the intersection of mutually perpendicular pivot axes with the normal to the mirror surface at its center substantially perpendicular to the pivot axes. The intersection of the pivot axes is very close to the front surface of the mount which allows the mirror surface to be desirably close to other elements of the optical system.
