STELLARNET has released the InGaAs spectrometer, covering the NIR wavelength range from 0.9μ-2.2μm. It is available from Warsash Scientific .
The units are packaged in small, rugged metal enclosures for portable, process, and lab applications. The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels, 25μm by 500μm tall, to provide maximum sensitivity. The detector has an integrated thermo-electric cooler (TEC) maintained at 5°C and stabilised within ±0.1°C.
The EPP2000-NIR-InGaAs spectrometers use single strand SMA 905 fibre optic input. Several models provide a variety of operational ranges and resolutions suitable for both spectroscopy and optical spectrum analysis.
NIR applications include chemical ID and moisture analysis, spectroradiometry and optical power measurements, laser characterisation, microsensor applications, and thicker thin-film measurements.
SpectraWiz software is included to accurately measure wavelength omissions, reflectance, transmission, absorption, and absolute intensities.
