The QE Pro-Raman-532 is a preconfigured spectrometer for 532 nm Raman excitation, using a 1200 lines/mm grating and 25 µm slit. Additional Raman configurations (for 785 nm excitation and other wavelengths) are possible using a custom-configured QE Pro spectrometer.
Designed with gold-coated mirrors and a back-thinned FFT-CCD detector, the QE Pro offers a low noise floor even at long integration times. Its ability to deliver sharp peaks from very weak Raman signals makes it an excellent choice for general Raman spectroscopy of chemicals and organic materials, which benefit from reduced autofluorescence that results in better overall signal to noise.
- 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
