  • Portable – small footprint, light weight, fiber optic-based spectrometer
  • Sensitive – high quantum efficiency detector
  • Powerful – signal-to-noise ratio of >1000:1
  • Stable – cooled detector allows low light detection and prevents spectral distortion

 

 

QE Pro-Raman is a preconfigured for 785 nm Raman excitation, using a 900 lines/mm grating H36 grating and 50 µm slit and includes Ocean View software.
