The mechanical design of Optical systems (Opto-Mechanical Design) is typically concerned with minimizing the
impact of the mechanical structure and environments on optical performance. Structurally insignificant loads may
induce unacceptable motion and/or distortion into the optical elements, which are summed along the optical path
resulting in total image blur and error. Optical system designs are therefore extremely sensitive to mounting
configurations and structural dynamic characteristics of the mechanical system. A process for efficient design
investigation is discussed that provides rapid system and individual optical element error predictions for mechanical
system design. Topics include discussions of fundamental Opto-Mechanical design considerations, Pro/E model
modification to facilitate automesh techniques, various automesh approaches using MSC/PATRAN and
Pro/Engineer, tet4 vs tet10 element performance and accuracy with MSC/NASTRAN, Line Of Sight (LOS) error
predictions, and Zernike polynomial calculations for optical surface aberrations using the MSC/OPOLY utility and
Code V.
