2-13 µm IR PHOTOCONDUCTORS THERMOELECTRICALLY COOLED

Description

The PC-2TE-λopt photodetectors series (λopt - optimal wavelength in micrometers) feature IR photoconductive detector on two-stage thermoelectrical cooler.

The devices are optimized for the maximum performance at λopt. Cut‑on wavelength is limited by GaAs transmittance (~0.9 µm). Bias is needed to operate photocurrent. Performance at low frequencies (<20 kHz) is reduced due to 1/f noise. 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 TO8 packages with wAl2O3 or wZnSeAR windows. Other packages, windows and connectors are also available.
