Abstract

The Near Infrared Camera (NIRCam) instrument for NASA's James Webb Space Telescope (JWST) includes numerous optical assemblies. The instrument will operate at 35K after experiencing launch loads at ~293K and the optic mounts must accommodate all associated thermal and mechanical stresses, plus maintain exceptional optical quality during operation. Lockheed Martin Space Systems Company (LMSSC) conceived, designed, analyzed, assembled, tested, and integrated the optical assemblies for the NIRCam instrument. With using examples from NIRCam, this paper covers techniques for mounting small mirrors and lenses for cryogenic space missions.
