IR photovoltaic detection module NIPM-I-5

HgCdTethermoelectrically-cooled

2.9 – 5.5 µm and over 1.8 MHz, with two HgCdTe thermoelectrically cooled, optically immersed photovoltaic detectors NIPM-I-5 is an infrared detection module designed for differential optical signal detection. The device can operate in balanced and auto-balanced mode. This detection module uses two individual detectors based on HgCdTe heterostructure. These IR detectors (signal and reference) are precisely matched to achieve a very high Common Mode Rejection Ratio (CMRR). NIPM-I-5 is dedicated to operating in systems where excess noise of radiation dominates, e.g. in the laser and some FTIR spectrometers. Features Two channels with similar spectral characteristics and frequencies Manual change of balanced or auto-balanced mode Low noise operation and high detectivity Integrated with fans and thermoelectric cooler controllers Single power supply Compatible with optical accessories Detectors type: PVI-4TE-5-1×1-TO8-wAl2O3-36 Applications QCL lasers excess noise suppression in gas analysis
