Uncooled infrared sensor
8 - 11 µm | PVMI Series
VIGO System
The PVMI-n (where n is optimal wavelength (λop),, in micrometers, to which the detector is optimized) series photodetectors are multiple heterojunction photovoltaic IR detectors, which have been optically immersed to high refractive index GaAs hyperhemispherical (standard) or hemispherical (option) lenses. These devices especially useful as large area detectors operating within 2 to 11 µm range. High performance and stability were achieved by using band gap engineered (HgCdZn)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-39 or BNC-based packages with no windows. Other packages, windows and connectors are available upon request. See application notes for more details.
