In the application under extreme low light conditions QE65000 apply to applications under low light conditions, fluorescence, Raman spectroscopy, DNA sequencing, astronomy and thin-film reflection. In complete fluorescence measurement system, PX-2 pulsed xenon light source is used to excite the CUV-ALL-way sampling stent samples. Ocean Optics also offers a solid-state secondary fluorescence standard STAN-FL-RED, can quickly and easily test and calibration system performance and stability. Quantum efficiency as high as 90% QE65000 spectrometer manufactured using a Hamamatsu FFT-CCD detector can be achieved (defined as the photon conversion efficiency of a photoelectron) up to 90% of the quantum efficiency. Unlike other spectrometers used in linear CCD detector area array CCD detector in the vertical direction 64 pixels, rely on the internal circuitry of the CCD signal is integrated to improve the signal to noise ratio (1200: 1) and the signal processing speed while linear CCD signal can only be handled by an external digital circuitry. Enhanced sensitivity of the system due to the full use of the area CCD slit height direction of the incident light, thereby greatly enhancing the QE65000 system sensitivity. In Ocean Optics spectrometer, by selecting different slit width control goes to the light intensity of the optical table. And now most of the spectrometer linear CCD detectors are used, so the slit height direction of the incident light system will not be fully utilized, while QE65000 research grade spectrometer is used in area array CCD, it is possible to collect more light, It is ideal for low brightness fluorescence applications.
