PVMI-2TE



8-11 μm IR PHOTOVOLTAIC MULTIPLE JUNCTION DETECTORS THERMOELECTRICALLY COOLED OPTICALLY IMMERSED

Description

The PVMI-2TE-λopt photodetectors series (λopt - optimal wavelength in micrometers) feature IR multiple junction optically immersed photovoltaic detector on two-stage thermoelectrical cooler.

The devices are optimized for the maximum performance at λopt. Highest performance and stability are achieved by application of variable gap HgCdTe 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 TO8 packages with wZnSeAR windows. Other packages, windows and connectors are also available.

  • High performance in the long wavelengths range without LN-cooling
  • Fast response
  • No flicker noise
  • Convenient to use
  • Wide dynamic range
  • Compact, rugged and reliable
  • Low cost
  • Prompt delivery
  • Custom design upon request
