QE PRO-ABS Fiber Optic Spectrometer for Absorbance by Ocean Optics




The QEPRO is the most sensitive spectrometer we have ever developed. The Hamamatsu FFT-CCD detector used in the QE65PRO-ABS 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). Excellent UV Response — Because the detector in the QEPRO-ABS is back-thinned (or back-illuminated), it has great native response in the UV and does not require phosphor coatings that are typically applied to other CCD detectors.  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
