Paper Abstract

The Near InfraRed Camera (NIRCam) for the James Webb Space Telescope (JWST) is a refracting instrument. Its unique optical performance derives from the Lithium Fluoride, Barium Fluoride and Zinc Selenide lenses that provide aberration and color correction over the large operating wavelengths, 0.6-5 microns. This paper describes cryogenic test results of the mounted camera lenses in a flight-like configuration. These data, which evaluate the foundation for NIRCam optical performance, reveals design strengths and challenges. This is a follow-up paper from SPIE paper 590409 (1) which presented the initial camera lens design.
