Two optical modules, mounted back to back, comprise JWSTs NIRCam (Near Infrared Camera) instrument. Each
module contains a short wavelength (SW) and long wavelength (LW) path. The instrument will be mounted to the ISIM
(Integrated Science Instrument Module) of the spacecraft via a mechanical support structure. Within a fourteen month
timeframe this aerospace structure was conceived, designed, analyzed, manufactured, integrated, tested and qualified for
flight. This paper describes the technical product and its fast, affordable, and successful evolution from concept design
to flight qualification, including critical decision points and lessons learned.
