Abstract
An optical mounting apparatus comprises an upper support assembly and a lower post assembly. The upper support assembly includes a stageplate mounted on a backing plate by a three point suspension mechanism. By locating an optical element mounting region at the corner of a rectangle defined by the three suspension points, a datum point within the region can be rotationally adjusted without simultaneous translational adjustment by manipulating only two of the three suspension points. The baseplate is mounted on a support rod which is slidably received in a casing. A lever arm having a surface which engages the support rod can be moved relative to the casing for selectively locking the rod in place.
