Andor’s iDus InGaAs 492 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.
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 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.
0.8 to 2.2 µm – Operating wavelength range
Peak QE of > 70% – 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
