8-11 μm IR PHOTOVOLTAIC MULTIPLE JUNCTION DETECTORS

Categories:
Detectors
Multiple junction

The PVM-λopt photodetectors series (λopt - optimal wavelength in micrometers) feature IR multiple junction photovoltaic detector. 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. Standard detectors are available in TO39 or BNC packages without windows. Various windows, other packages and connectors are available upon request.

Characteristics:

Features:

  • Ambient temperature operation
  • No bias required
  • Short time constant
  • No flicker noise
  • Operation from DC to VHF
  • Perfect match to fast electronics
  • Wide dynamic range
  • Large area devices
  • Low cost
  • Prompt delivery
  • Custom design upon request
