Paper Abstract

Optomechanical sensitivity is the amount of image quality degradation in response to a certain deviation of any primary parameter of an optomechanical system. The sensitivity depends not only on the optical system but also on the mechanical layout. A technique for calculation of optomechanical sensitivity is presented. Only mechanical parameters are used as primary parameters. It is shown that airspaces or element tilts and decentrations cannot be used as primary parameters. The tolerances of an optomechanical system can be determined based on the computed sensitivity. Edge Function is used to evaluate the image quality for projection lenses. Software for realization of this technique has been developed. Examples of optimization of the optomechanical system of a projection lens using the developed technique are presented.
