Description

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 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.

Features

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
