QE PRO Raman 785nm Fiber Optic Spectrometer

The QEPro-Raman is the most sensitive Raman spectrometer we have ever developed. The Hamamatsu FFT-CCD detector used in the QEPRO-Raman provides 90% quantum efficiency. The 2D area detector allows for binning a vertical row of pixels, which offers significant improvement in the signal-to-noise ratio (>1000:1).  Features user changeable slits and even user changeable SMA to FC fiber ports.

Portable– small footprint, light weight, fiber optic based spectrometer for the field

Sensitive – high quantum efficiency detector

Powerful – signal-to-noise ratio of >1000:1

Stable – cooled detector allows low light detection and prevents spectral distortion

The standard system is set up to work with a 785nm laser. You can order one set up for 532nm lasers (pricing is the same for the spectrometer).

QE Pro-Raman is a preconfigured spectrometer for Raman spectroscopy and includes:

Optional internal shutter, software controlled  select under options
