Description
StellarNet’s high performance InGaAs extended range spectrometers cover the NIR wavelength range from 0.9 - 1.7 μm in one unit. These InGaAs spectrometers are exceptionally robust with no moving parts and are packaged in small rugged metal enclosure (2.75” x 4” x 6”) for portable, processes, and lab applications. The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels (1024 optional) 25 μm by 500 μm tall to provide best signal performance. The detector has an integrated two-stage thermo electric cooler (TEC) maintained at -15 °C, stabilized within +/-0.1°C. The InGaAs spectrometer DWARF-Star uses single strand SMA 905 fiber optic input.
All DWARF-Star units can be coupled with StellarNet’s BLACK-Comet or UVN-SR units to cover the entire 200 - 2300 nm range. Coupling the units can provide you with quick analysis of color in the visible spectrum and additionally compound analysis though compound fingerprint identification in the near infrared spectrum.
NIR applications include chemical ID and moisture analysis, SpectroRadiometry and optical power measurements, laser characterization, microsensor applications, and thicker thin-film measurements.
Several units may be daisy chained via a USB-2 hub allowing simple configurations for dual and multi-beam process applications.
The powerful SpectraWiz® 32 bit spectrometer software is provided free of charge with every spectrometer instrument. This includes drivers and customizable software for operation on all current Windows operating systems. The SpectraWiz software is considered the "Swiss Army Knife of Spectroscopy" and may be used to accurately measure wavelength emissions, reflectance, transmission, absorption, concentrations, and absolute intensities. In addition to real-time spectroscopy, SpectraWiz® has built-in applications for SpectroRadiometry, SpectroColorimetry, ChemWiz chemistry lab concentration analyzer, and UV level monitors.
