Andor iDus 1.7µm InGaAs Spectroscopy Cameras

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.

0.6 to 1.7 µm – Operating wavelength range

Peak QE of > 85% – High detector sensitivity

TE cooling to -90°C – Negligible dark current without the inconvenience of LN2

UltraVac™ – Permanent vacuum integrity, critical for deep cooling and sensor performance

Single window design – Delivers maximum photon throughput

25 µm pixel width option – Ideal for high-resolution NIR spectroscopy

Simple USB 2.0 connection – USB plug and play – no controller box. Inputs & Outputs: External Trigger, Fire and Shutter TTL readily accessible. I2C for the more adventurous user

Software selectable output amplifiers – Allows user to optimize operation with choice of High Dynamic Range (HDR) or High Sensitivity (HS) modes of operation

Minimum exposure time of 1.4 µs – Enables higher time-resolution and minimization of dark current contribution for applications with reasonable signal level
