The QE Pro-Raman product family comprises preconfigured spectrometers for 532 nm, 638 nm or 785 nm Raman excitation.
Designed with gold-coated mirrors and a back-thinned FFT-CCD detector, QE Pro-Raman spectrometers offer a low noise floor even at long integration times. The ability to deliver sharp peaks from weak Raman signals makes QE Pro-Raman spectrometers an excellent choice for Raman analysis of chemicals, pharmaceuticals, illicit drugs, explosives and organic materials.
The 785 nm Raman excitation option -- the QE Pro-Raman+ -- has optical bench enhancements that provide even greater sensitivity, giving users the ability to detect even weaker Raman signatures.
- Portable – small footprint, light weight, fiber optic-based spectrometer
- Sensitive – high quantum efficiency optical design
- Powerful – signal-to-noise ratio of >1000:1 (single acquisition)
- Stable – cooled detector allows low light detection and extremely long integration times
