Description

PV-4TE-λopt photodetectors series (λopt - optimal wavelength in micrometers) feature IR photovoltaic detector on four-stage thermoelectrical cooler. The devices are optimized for the maximum performance at λopt. Cut-on wavelength can be optimized upon request. Reverse bias may significantly increase speed of response and dynamic range. It results also in improved performance at high frequencies, but 1/f noise that appears in biased devices may reduce performance at low frequencies.

Highest performance and stability are achieved by application of variable gap (HgCd)Te semiconductor, optimized doping and sophisticated surface processing. Custom devices with quadrant cells, multielement arrays, different windows, lenses and optical filters are available upon request.

Standard detectors are available in TO-8 packages with BaF2 windows. Other packages, windows and connectors are also available.
