Specifications include, but are not limited to: The Arizona Infrared Detector Laboratory (AIRD) is being established by Steward Observatory and the Department of Astronomy at the University of Arizona to bolster the University’s capability and expertise in the development and characterization of IR detectors and instrumentation. To achieve these goals, AIRD is seeking a cryogenic test station for the testing of Infrared focal plane arrays (FPAs) and their associated focal plane electronics (FPEs). This dewar will be used by the AIRD team as a multi-purpose utility test station for current and future infrared detector projects supporting multiple FPA designs and environments. The limiting use case for these test dewars is provide detector-limited (i.e. low thermal background) test capabilities for a 15um-cutoff FPA, an operating temperature of 30K with a FPA power dissipation of 1W, and illumination uniformity better than 10% over at least an 8cm x 8cm area. We desire a proposal for the design, fabrication, and test of one (1) of these cryogenic FPA test stations with the scope of work as follows and meeting the requirements in Table 5.1 with optional equipment as specified in Table 5.2
