StellarNet high performance near infrared spectrometers cover the NIR wavelength range from 900-2500nm. 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.
DWARF-Star 900-1700nm
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!
NIR-HR-X
Extreme High resolution NIR spectrometers available for wavelength monitoring applications. High resolution optics provide optical spectrum analysis down to 0.2nm resolution.
RED-Wave 900-2500nm
Measure far into the NIR with an extended InGaAs array. Available for range 900-2500nm. Great for liquid absorption measurements, optical transmission, and laser wavelength characterization
STELLARCASE-NIR
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.
NIR-HR
High resolution NIR spectrometers available for wavelength monitoring applications. High resolution optics provide optical spectrum analysis down to 0.4nm resolution.
ChemWiz ADK Handheld NIR Spectrometer
Rugged handheld NIR spectrometer for material identification and composition analysis using NIR spectroscopy. The ChemWiz-ADK (Analyzer Development Kit) includes onboard easy to use chemometrics for PLS model building and deployment as well as spectral ID matching functions.
