Near-Infrared Reflectance Spectrometer

Polychromix DTS-1700 NIR Spectrometer – 930nm to 1690nm – Near Infrared – InGaAs

The DTS-1700™ uses a MEMS spatial light modulator featuring a single InGaAs detector. It covers the 930-1690 nm wavelength range and uses the Digital Transform Spectroscopy (DTS™) Technology. Polychromix’s DTS™ Spectrometer uses a grating for spectral dispersion onto the MEMS spatial light modulator. Each spectral region can be modulated on or off and then measured by the system’s single-element InGaAs detector in a timed sequence. The resulting time-varying transform is processed to create a spectrum. The DTS™ technology automatically corrects for stray light.
