■ DESCRIPTION

The PVI-2TE-n (where n is wavelength A,_op, in micrometers, to which the detector is optimized) series photodetectors are two-stage TE-cooled IR photovoltaic detectors, which have been optically immersed to high refractive index GaAs (or CdZnTe) hyperhemispherical (standard) or hemispherical (option) lenses. These devices can be optimized for the maximum performance anywhere within 2 to 11 um range. High performance and stability were achieved by using a variable gap (Hg,Cd,Zn)Te semiconductors, optimized doping and improved surface processing. Custom devices with quadrant cells, multielement arrays, various immersion lenses, windows and optical filters are available on request.

Standard detectors are available in modified TO-8 packages with BaF₂windows. Other packages, windows and connectors are available upon request. See application notes for more details.

Multiple cells connected in series are preferable for large area devices. They are characterized by similar D*, larger parallel resistance and lower Rj.
