NIR Spectrometers
StellarNet high performance near infrared spectrometers cover the NIR wavelength range from 900-2300nm. The units are exceptionally robust with no moving parts and are packaged in small rugged metal enclosures for portable, process, and lab applications. The NIR 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. Wavelength Opto-Electronic is the partner of StellarNet brand of spectrometers for Southeast Asia.
