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. This QE PRO-ABS Ocean Optics spectrometer 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
