The wide-field infrared explorer (WIRE) is a small spaceborne cryogenic telescope specifically designed to study the evolution of starburst galaxies. The use of advanced, large format, infrared hybrid focal plane array technology provides a large sensitivity gain over previously flown missions. The hybrid focal plane arrays (HFPAs) used in this instrument are 128 by 128-element arsenic-doped-silicon blocked impurity band infrared detector arrays connected via indium column interconnects to matching cryogenic multiplexers. The WIRE instrument includes two focal plane mount assemblies (FPMAs), each of which includes a HFPA optimized for a particular wavelength band. Details concerning design, fabrication and performance of the critical components of the WIRE FPMAs are described.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.
