MCT photoconductive detector products

Model KMPC12-1-J1
MCT photoconductor/ preamplifier

Description

Model KMPC12-1-J1 series is MCT photoconductive infrared detector /preamplifier with cutoff wavelength greater than 12 um, 14 um, 16 um, 18 um or 22um. The MCT photoconductive detector is coupled to an internal 20Hz to 1 MHz bandwidth amplifier, with BNC output. Detector active areas range from 0.05 to 4mm. The side looking LN2 pour filled Dewar has a 12 hour hold time.

Detector to preamplifier connections are inside the Dewar, minimizing electrical pick up and simplifying system integration. This low noise preamplifier is matched to the detector characteristics and provides optimum bias voltage to the detector. The only connections required are to the preamplfiear signal output and preamplifier power.
