StellarNet NIR3-HR 水质光度计和色度计

"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 (2.75â€� x 4â€� x 6â€�) 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 â€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."
