Andor iDus InGaAs 491 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 -90ºC where the best signal-to-noise ratio can be achieved for the majority of the applications in this spectral region.
• 0.6 to 1.7 μm
• Peak QE of > 85%
• TE cooling to -90°C
• UltraVac™
• Single window design
Andor's iDus InGaAs 1.7 array detector series provides the most optimized platform for Spectroscopy applications up to 1.7 µm. The TE-cooled, in-vacuum InGaAs camera 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.
