Large format LWIR MCT FPAs will be a valuable asset for a variety of earth science and astrophysics experiments which require IR imaging. The fabrication of large format LWIR MCT FPAs with high quantum efficiency and broad spectral response out to 12 microns will greatly increase the imaging capability of Discovery 13/14, New Frontiers 4, Europa Jupiter System, Mars 2018 and other space exploration missions. A single detector and small-array product line would have a range of commercial applications, such as spectrometry, thermometry, high-end industrial manufacturing and hotspot detection. Additionally, larger arrays will have applications in geophysics, geology, law enforcement, medical imaging systems, commercial airline landing aids, ground transportation safety. remote environmental sensing, search and rescue, and emergency response including firefighting.
