Ocean Optics QE65000 Scientific-grade Spectrometer

QE65000 Scientific-grade Spectrometer combines the power of a backthinned FFT-CCD detector with advances in a proprietary optical bench coating and other components to provide high sensitivity and superior dynamic range for a host of low-light level applications. Add the spectrometer’s onboard thermoelectric cooler to the mix, and the new QE65000 presents an ideal option for applications such as fluorescence, Raman analysis and DNA sequencing.

New! Optical Bench Enhancements

The great performance of our QE65000 Spectrometer has been enhanced to provide even more value: lower stray light, improved efficiency in the UV and Shortwave NIR, and better unit-to-unit reproducibility. For full UV-Shortwave NIR coverage, you'll want to configure your QE65000 with our HC-1 composite grating.

Ocean Optics is also offering a proprietary low BRDF bench coating to improve stray light performance and provide better reproducibility in unit-to-unit performance.

Quantum Efficiency to 90%

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). Ocean Optics 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.

Increased System Sensitivity

In Ocean Optics spectrometers with linear CCDs, the slit’s width, not its height, regulates the amount of light entering the bench because linear CCDs cannot efficiently collect the light from the entire height of the slit. But in the QE65000, the 2D area detector can better take advantage of the height of the slit and the additional light, greatly improving system sensitivity.

Excellent UV Response

Because the detector in the QE65000 is back-thinned (or back-illuminated), it has great native response in the UV and does not require the additional coatings that we typically apply to other detectors for UV applications.

Demanding Low Light-level Applications

The QE65000 Spectrometer is a great option for low-light level applications including fluorescence, Raman spectroscopy, DNA sequencing, astronomy and thin-film reflectivity. The TE-cooled (down to -15 °C) detector features low noise and low dark signal, which enables low-light-level detection and long integration times (analogous to the shutter speed of a camera) from 8 milliseconds to 15 minutes, with virtually no spectral distortion.

Onboard Programing

The QE65000 also has an onboard programmable micro-controller for controlling the spectrometer and accessories. You have access to 10 user-programmable digital inputs/outputs and a pulse generator for triggering other devices. You can use the I/Os to flash a lamp, stop/start a process, and send a message/alarm during the spectrometer’s integration period. The spectrometer’s operating parameters can be controlled through software. In fact, wavelength calibration coefficients unique to each spectrometer are programmed into a memory chip right on the spectrometer.

Optical Bench Options

At Ocean Optics, we understand that your work is unique and that you want a spectrometer to fit your specific needs. With the QE65000 Spectrometer, you can configure the bench for your application. Choose QE65000 Optical Bench Options such as entrance aperture size, detector accessories, filters a grating and more. Our application scientists will help you determine which configuration will best work for you.
