QEPRO-RAMAN-638PLUS Spectrometer
The QE Pro-Raman+ has optical bench enhancements with respect to QE Pro-Raman that provide even greater sensitivity, giving users the ability to detect even weaker Raman signatures.
QE Pro-Raman+ product family comprises preconfigured spectrometers for 532 nm and 638 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.
QEPRO-RAMAN-638PLUS Spectrometer
Features
