StellarNet high performance InGaAs 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.
Our most popular model. Extremely versatile and robust with Czerny Turner optics and our standard range InGaAs array for ranges 900-1700nm. Available with many wavelength range configurations as well has high resolution models. Works great for most applications!
Measure far into the NIR with an extended InGaAs array. Available for range 900-2300nm. Great for liquid absorption measurements, optical transmission, and laser wavelength characterization
Rugged and fully integrated portable Case System for material identification and composition analysis using NIR spectroscopy. The StellarCASE-NIR includes interior mounting of spectrometer instrumentation pre-configured for “Open & Measure” application, with no additional setup required.
Newest to the line-up, the NIR-Micro allows for an even smaller spectrometer package and uses MEMs technology with a single element InGaAs detector for superior performance. Range 1750-2150nm
