Provide two windowing focal plane array (FPA) Infrared (IR) imaging systems to meet requirements for two specific instruments identified as 1) MWIR Indium Antimonide (InSb) High Resolution and 2) LWIR Strained Layer Superlattice (SLS) High Speed. Each of the two types has specific radiometric performance requirements, while both instruments must share common operational characteristics and software (in two discrete systems). These two systems will be used to upgrade an existing multi-spectral imaging system. Both requirements are intended to be fulfilled by off-the-shelf commercially available systems and shall use common control/data recording software.
