The paper presents the new infrared detection module developed at the VIGO System Ltd. Its high sensitivity of was achieved by both matching the IR detector to the preamp and minimizing noises. High sensitivity of the detector was achieved by using photodiodes with immersion lens. Immersion lens enables optimization of the detector area, decreasing detector capacity and time constant. Detector noise was reduced as a result of photodiode cooling by means of a thermoelectric cooler and reverse biasing. Developed module is dedicated to NOx optoelectronic sensors operates basing on Cavity Enhanced Absorption Spectroscopy technique.
