Raman Spectrometer, Modular, High Sensitivity

Manufacturer's part number :

QE Pro-Raman

Manufacturer Ocean Optics

Ocean Optics

Description :

The sensitivity and large dynamic range of the QE Pro-Raman combine to make it the highest-performance miniature spectrometer in its class. Absorption, reflectance, fluorescence and Raman measurements all benefit from the superior performance of the QE Pro-Raman. For advanced measurements, a 15,000 spectra buffer ensures data integrity at high collection rates and an advanced optical design and thermoelectric cooler combine to provide thermal stability over long-term measurements. Whether for high speed or wide concentration range measurements, the QE Pro brings exceptional performance to your lab or process application.

Wide Dynamic Range: Low-noise electronics and an 18 bit A/D converter double the QE Pro’s dynamic range and increase the sensitivity by a factor of two compared to typical back-thinned CCD array miniature spectrometers.
