8-11 μm IR PHOTOVOLTAIC MULTIPLE JUNCTION DETECTORS

Description

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.
