<p>An optical mounting apparatus (10) comprises an upper support assembly (12) and a lower post assembly (14). The upper support assembly (12) includes a stage plate (21) mounted on a backing plate or baseplate (22) by a three point suspension mechanism. By locating an optical element mounting region (16) at the corner of a rectangle defined by the three suspension points, a datum point (60) within the region (16) can be rotationally adjusted without simultaneous translational adjustment by manipulating only two of the three suspension points. The baseplate (22) is mounted on a support rod (94) which is slidably received in a casing (70). A lever arm (80) having a surface (98) which engages the support rod (94) can be moved relative to the casing (70) for selectively locking the rod (94) in place.</p> |
