The WF/PC is designed for use on the Hubble Space Telescope (HST). It has complex optics with tight alignment and design requirements. The camera is subjected to various static, dynamic and thermal environments during its ten plus years life. To ensure the camera meets its design objectives and functions properly on orbit, an extensive structural analysis was performed using MSC/NASTRAN. This paper describes the camera, its analysis, and shows the versatility of the finite element method applied to an optical system.
