Infrared Systems Development Corporation offers multi-channel preamplifiers for small and large array detectors. These preamplifiers are the same high quality low noise amplifiers as the single channel unit, packaged in multi-channel housings. Bias and Gain adjustments allow corrections for signal differences between array elements. Each element can be adjusted to compensate for responsivity variations.
Bias and Responsivity (gain) of each individual array element can be tuned to provide uniform response from all elements. Front Panel input BNC connectors attach to the detector terminals and Rear Panel output BNC's connect to signal acquisition and analysis circuitry. Low impedance output (50 Ohm) allows direct connection to PC based A/D boards, and drive long length cables. Several multi-channel arrays can be used for larger arrays; two MCT-6400's will interface with a 128 Element array.
