Description

The PVMI-nTE-N (where N is wavelength λop, in micrometers, to which the detector is optimized and n is number of TE stages) series photodetectors are two-stage TE-cooled IR photovoltaic detectors, which have been optically immersed to high refractive index GaAs hemispherical or hyperhemispherical lenses. These devices can be optimized for the maximum performance for long wavelength, large area devices. High performance and stability were achieved by using using band gap engineered semiconductors (HgCdZn)Te, optimized composition/doping profiles and improved surface processing.

Standard detectors are available in modified TO-8 packages with BaF2 windows.

Other packages and windows are available upon request. See application notes for more details.

Custom devices with quadrant cells, multielement arrays, specialized packages, connectors, windows and optical filters are available on request.
