Overview
Andor iDus InGaAs 1.7 and 2.2 array series provide the most compact and optimized research-grade platform for Spectroscopy applications up to either 1.7 or 2.2 μm. The Thermo-Electrically cooled, in-vacuum sensors reach cooling temperatures of -90℃ where the best Signal-to-Noise ratio can be achieved for the majority of the applications in this spectral region. Beyond this cooling point Blackbody radiation from any elements facing the sensor will dominate the dark signal, and since Quantum Efficiency will be impacted with decreasing cooling temperature TE cooling will allow access to optimum signal-to-noise performance
