SNIR-8 Series
Near Infread Spectrophotometer

SNIR-826 is self-developed by Stalwart to replace NIR Quest aiming features high performance cost less, 900-2600nm NIR, Near Infrared spectrometer with 512 pixels, InGaAs cooled down to -20ºC, resulting in low noise, 2 times higher SNR, better reliability, measuring results do not change with ambient temperatures.

Allow for custom or preconfigured wavelength range, resolution by changing grating lines or slit size. Three common standard maximum wavelength are SNIR-817 900-1700 nm, SNIR-821 900-2100 nm , SNIR-826 900-2600 nm.

Crossed C-T optical bench design the higher sensitivity improve measure accuracy and detect tiny change spectrum, the optimized optical resolution level is superior for NIR spectrometer manufacturing.

  • SNIR-860 covers 900-2500nm NIR spectrometer developed by Stalwart for customers have less budget NIR requirements.
  • It uses cooled InGaAs detector with 512 pixels, Cooled down to -20ºC.
  • Compact size fit to a wide system integration in industrial measurement.
  • SMA905 fiber input or free-space
  • USB powered and 5V DC UART power
  • Free SDK package for OEM customers integration
