512, 1024 Active Pixels; Pixel Size 25/50x250 µm; 16 bit; USB 2.0

Andor iDus InGaAs 491 and 492 arrays provide the most compact and optimized research-grade platform for spectroscopy applications up to either 1.7 or 2.2 μm. The TE-cooled, in-vacuum sensors reach cooling temperatures of -90°C where the best signal-to-noise ratio can be achieved for the majority of the applications in this spectral region.

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.

Key Features:

  • Operating Wavelength Range from 0.6 to 2.2 μm
  • Peak QE up to > 85% for High Detector Sensitivity
  • TE cooling to -90°C: Critical for Elimination of Dark Current Detection Limit - No Inconvenience Associated with LN2
  • UltraVac™
  • Single Window Design Delivers Maximum Photon Throughput

Specifications:

Active Pixels 512, 1024
Pixel Size 25/50x250 µm
Resolution 16 bit
Interface USB 2.0
