A Thermo-Electric Cooling Approach to SWIR Spectroscopy with InGaAs Array Detectors

Historically performing low-light Spectroscopy in the Short Wave Infrared Region (SWIR) has been undertaken with Liquid Nitrogen (LN2)-based InGaAs array detectors to access the lowest sensor dark current possible.

This webinar will explore the actual effect of InGaAs array cooling on Signal-to-Noise Ratios (SNR) by considering not only sensor dark noise, but also sensor Quantum Efficiency evolution with temperature and experimental setups black body radiation contributions. We will also discuss the suitability and advantages of Thermo-Electrically (TE) cooled approach to InGaAs sensor technology over LN2 for SWIR Spectroscopy, both from a performance and user convenience perspective.
