■ DESCRIPTION
The PEM séries detectors operate on the photoelectromagnetic effect photovoltage in the semiconductors. The devices are typically optimized for the best performance at 10.6 um. PEMI have been optically immersed to high refractive index GaAs (or CdZnTe) hyperhemispherical (standard) or hemispherical (option) lenses. The detector include a quaternary semiconductor (Hg-Cd-Zn-Te) with selected composition and doping profiles, and of miniature permanent magnets to produce very strong magnetic fields.
The PEM detectors are exceptionally well suited for hétérodyne détection of 10.6 um radiation. Exhibiting no flicker noise, they can be at the same time used for détection of CW and low frequency modulated radiation in the whole 2 to 12 um spectral range. Custom detectors such as for e.g. single éléments of various sizes, quadrant cells and multielement arrays, various specialized packages and connectors are available upon request.
