The Model 663-10 Indium Gallium Arsenide Detector features an NIR response, and is both TE cooled and stabilized. This is a high-performance photodiode/receiver operated through the use of a thermoelectric cooler, and it is fitted with a dual gain input transimpedence amplifier.
For this device, output voltage is always proportional to input signal, and it comes with an integral FET amplifier. This is a complete system that will fit into McPherson slit assemblies, but buyers should take care to shield the unit from stray light when in operation in order to prevent the amplifier from becoming saturated, as this could lead to device failure. A bias is supplied and the unit is mounted to a mounting flange.
