Product description

Reach more sesitivity, better SNR and faster measuremetns in a compact design. With an input f/2.0 you can collect more light and using scientific-grade detectors to detect more light. The patented high transmission VPH gratings & diffraction-limited optics are keeping more light to receive highest sensitvity. 
You can configure your own spectrometer or system with the performance you need by choosing between options for resolution, detector cooling, and sample coupling. 


  • Wavelength range is 250 - 850 nm
  • industry-leading high efficiency optics
  • f/2.0 input to capture more light
  • patented VPH transmission gratings
  • high sensitivity for fast data sampling rates
  • linear absorbance up to 3.7 AU at 300 nm
  • low stray light for superior LOD
  • fiber coupled & free space models
  • compact, robust & configurable
