Paper Abstract
The Near Infrared Camera (NIRCam) instrument for NASA's James Webb Space Telescope (JWST) has an optical
prescription which employs three triplet lens cells. 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 an
exceptional wavefront during operation. The Lockheed Martin Advanced Technology Center (LMATC) has built and
tested the collimator and camera optics for use on the NIRCam flight instrument. This paper presents an overview of the
driving requirements, a brief overview of the changes in the opto-mechanical design and analysis since our last
presentation, a discussion of the collimator and shortwave camera triplet assembly processes, and finally a summary of
the mechanical and optical test results.
