Self balancing infrared cooling detector

NIPM-I-5（-8）Self balancing infrared cooling detectorIt is a dual channel detection device that includes signal measurement and reference channels, and can operate in two modes: manual balancing and automatic balancing,Suitable for detecting various infrared optical signals. The device uses two separate TE cooled mercury cadmium telluride infrared detectors equipped with immersion lenses, respectively for signal detection and reference channels. These two detectors and their supporting circuits have been precisely matched, and their performance parameters are almost identical, making the two channels have a high common mode rejection ratio CMRR, which can effectively eliminate various environmental noise factors introduced on the measurement channel.

NIPM-I-5（-8）Self balancing infrared cooling detectorIt is particularly suitable for use in gas measurement systems where the noise of the laser is much greater than the inherent noise of the detector, and the system noise is mainly composed of laser noise.

Features:

1) The signal measurement and reference dual channels have similar spectral and frequency characteristics;

2) Can work in both manual and automatic balancing modes;

3) Low noise and high detection rate, close to the background noise limit (BLIP);

4) TE is integrated into the deviceRefrigeration controller andAir cooled fan;

5) Single power supply;

6) Compatible with infrared optics such as optical lenses;

7) Detector model used: PVI-4TE-5 (PVI-4TE-8).

Main purposes:

Used for suppressing excessive noise in QCL lasers in gas detection and analysis systems.
