The Near Infrared Camera (NIRCam) instrument for NASA's James Webb Space telescope (JWST) is one of four science instruments to be installed into the integrated science instrument module (ISIM) on JWST for the purpose of conducting scientific observations over a five year mission lifetime. NIRCam is required to operate at 37 Kelvin to produce high resolution images in two-wave bands ranging from 0.6 to5 microns. A relatively recent requirement for the NIRCam instrument is to provide a means of imaging the primary mirror for ground testing, instrument commissioning, and diagnostics throughout the mission. This paper discusses the development of the pupil imaging lens (PIL) assembly. In addition to detailing the driving requirements, this paper briefly covers the mechanism design and delves more deeply into the engineering of the optical design.
