Description
The PC-TE-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 wedged BaF2 windows. Other
packages, windows and connectors are also available.
