Abstract

The various optical elements in a sophisticated optical system must be precisely aligned to each other to obtain an aberration-free image. In optical systems with very tight alignment tolerance requirements, the optics and their mounts are usually manufactured to rather loose tolerances, and adjustment mechanisms are then used to align the optics relative to each other at assembly. Another class of adjustment mechanisms is employed to move one or more optical elements of a system in real time to compensate for the image degradation due to environmental effects. This paper discusses the three basic types of adjustment mechanisms namely: linear, rotary and tilt mechanisms. Each mechanism consists of a number of parts such as the actuator, locking and preloading components. The selection criteria for these components of the adjustment mechanisms are presented in detail. Finally, some design guidelines for applications of the adjustment mechanisms in complex optical systems are presented.
