Unified low light level photodetector modules FPM-UV, FPM-VIS and FPM-IR are intended for conversion of optical image in UV, visible and near –IR spectral regions into TV signal in wide irradiance range at input.
Devices include two cascade pre-commutating amplifier based on two image intensifiers of 2+ generation, coupled through direct optical-fiber contact with special wide format frame transfer CCD.
To block the visible range of the radiation spectrum in FPM-UV a combined bandpass UV-filter could be was used. The unified devices FPM have possibility of gating by e-gate of input image intensifier. Wide adjustable range of irradiance at FPM input of 104 is achieved by varying the gain of two image intensifiers.
