QM-10.6

HgCdTe (MCT) Four-Channel Detection Module

3.0 – 12.0 µm, DC – 1 MHz, with photovoltaic quadrant geometry multiple junction detector

QM-10.6 is „all-in-one” position IR detection module. Uncooled photovoltaic multiple junction quadrant geometry detector, based on HgCdTe heterostructure, is integrated with transimpedance, DC coupled four-channel preamplifier. It is designed to accurately measure the displacement of an incident beam relative to the calibrated center. This device is ideal for measuring the movement of a beam, the distance traveled, or as feedback for alignment systems.
