High-performance InSb, HgCdTe, and Impurity Band Conduction (IBC) Focal Plane Arrays (FPAs) are available with spectral responses from 0.4 µm to 28 µm for ground-based astronomy and space-based instruments. Raytheon Vision Systems (RVS) uses state-of-the-art facilities and processes to produce these arrays. The InSb and IBC arrays are available as standard products for astronomical applications, and custom arrays incorporating our latest multiplexer designs are also available in a variety of formats. Raytheon has also developed a double-layer heterostructure HgCdTe process for large-format arrays. Custom arrays using this process are available for those customers desiring HgCdTe with its ability to tailor the bandgap for cutoff wavelengths from 1.7 µm to 14 µm.
