Abstract

In this paper, simple relationships are presented to determine the amount of focal shift that will result from the axial motion of a single element or group of elements in a system. These equations can simplify first-order optomechanical analysis of a system. Examples of how these equations are applied are shown for lenses, mirrors, and groups of optical elements. Limitations of these relationships are discussed and the accuracy is shown in relation to modeled systems.
