LOT-Oriel has released the Andor iDus InGaAs detector array system, which is part of the iDus range of detectors. 


The iDus InGaAs can have 512 or 1024 element linear photodiode arrays (PDA), which is ideal for NIR spectroscopy with high sensitivity output and high resolution covering wavelengths from 800nm up to 2200nm.


The iDus InGaAs detector system includes a peak QE of >80 per cent - with low noise electronics, a  choice of 25 or 50μm pixel size - for high dynamic range and high resolution and USB 2.0 connectivity.


The detector system has a guaranteed hermetic vacuum seal, which is assembled in a Class 10,000 cleanroom facility and Andor's UltraVacT process optimises sensor performance (through higher QE and lower dark current) and ensures that this performance is retained year after year.


Other features of the iDus InGaAs detector system include thermoelectric (TE) cooling - to a minimum temperature of -85°C with water-assisted cooling for optimal S/N performance. Negligible dark current without the aggravation or safety concerns associated with LN2, a minimum exposure time of 1.4μ/s, software selectable output amplifiers - allowing user to optimise operation with choice of High Dynamic Range (HDR) or High Sensitivity (HS) modes of operation a single window design, Andor-Solis software with a Windows user interface - offering system integration, automation and advanced data manipulation facilities. Additionally we have Andor SDK software optimised for InGaAs and easy and complete interfacing - with Andor Shamrock spectrographs and third party spectrograph systems.
