Paper Abstract
The Near Infrared Camera (NIRCam) instrument for NASA's James Webb Space Telescope (JWST) has an optical
prescription which employs several mirrors, some of which are powered and some of which are flats that aid in
packaging. Two distinct designs for the mirrors and their mounts have been developed such that different requirements
for mass, packaging and induced wavefront error can be met. The instrument will operate at 37K after experiencing
launch loads at ~293K and the mounts must accommodate all associated thermal and mechanical stresses. Two of the
mirrors needed to be redesigned after initial prototype testing of one of the designs. This paper will provide an update
on the design and analysis status for all the mirrors including results of the initial prototype testing.
