Optical CCD spectrometer for scientific applications Ocean Optics

The QE65000 Scientific-grade Spectrometer is a novel combination of detector, optical bench and electronics technologies that provides users with a remarkably sensitive system for demanding low-light level applications such as fluorescence, DNA sequencing, astronomy and Raman spectroscopy. The QE65000 can achieve up to 90% quantum efficiency with high signal-to-noise and rapid signal processing speed.

The QE65000 is the most sensitive spectrometer we have ever developed. The Hamamatsu FFT-CCD detector used in the QE65000 provides 90% quantum efficiency (defined as how efficiently a photon is converted to a photo-electron). Most of our other detectors are linear CCDs but with this “2D” area detector, we can bin (or sum) a vertical row of pixels, which offers significant improvement in the signal-to-noise ratio (>1000:1) and signal processing speed of the detector compared with a linear CCD, where signals are digitally added by an external circuit.
