iDus 2.2µm InGaAs detector array for Spectroscopy

Andor's iDus InGaAs 2.2 array detector series provides the most optimized platform for Spectroscopy applications up to 2.2 µm. The TE-cooled, in-vacuum sensors reach cooling temperatures of -90°C where best Signal-to-Noise ratio can be achieved. Indeed dark current will improve moderately below -90°C where scene black body radiation will dominate, while Quantum Efficiency of the sensor will be greatly impacted at these lower temperatures and lead to a lower Signal-to-Noise ratio. 0.8 to 2.2 m Peak QE of > 70% TE cooling to -90°C UltraVac? Single window design.
