StellarNets’ high performance InGaAs spectrometers 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 RED-Wave NIR InGaAs spectrometers use single strand SMA 905 fiber optic input. Several models provide a variety of operational ranges and resolutions suitable for both spectroscopy and optical spectrum analysis.
Extended range systems for 1.5-2.2μm are available in 512 or 1024 element InGaAs PDA’s with 25 x 250um tall pixels. Because of reduced sensitivity and higher dark noise, the extended range InGaAs spectrometers are primarily used for measuring tunable lasers, characterizing optics, or chemical absorption & transmission thru cuvettes, flow cells, and dip probes.
