Red-Wave Nir Spectrometers With 512 or 1024 InGaAs Detector Arrays

The RED-Wave NIR spectrometers are equipped with high performance InGaAs PDAs to cover the NIR wavelength range from 0.9-2.3 μm. The units are exceptionally robust with no moving parts and are packaged in small rugged metal enclosures (2.75” x 4” x 6”) for portable, process, and lab applications. The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels (1024 optional) 25μm by 500μm tall to provide maximum sensitivity. The detector has an integrated thermo electric cooler (TEC) maintained at –10 °C, stabilized within +/-0.1 °C. The NIR spectrometers take a single strand SMA 905 terminated fiber optic cable with low OH as input. Several models provide a variety of operational ranges and resolutions suitable for both spectroscopy and optical spectrum analysis. The units interface to a PC via USB-2 and can be operated simultaneously with StellarNet UV-VIS spectrometers to provide a Dual-Detector Super-Range (Dual-DSR) spectroscopy system.
