2-11 µm IR PHOTOCONDUCTORS

Photoconductive

The PC-λoptopt - optimal wavelength in micrometers) feature IR photoconductive detector.

This series is easy to use, no cooling or heatsink needed. 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.

Standard detectors are available in TO39 or BNC packages without windows. Various windows, other packages and connectors are available upon request.
