New! Optical Bench Enhancements
The great performance of our QE65000-Raman 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.
We are 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-Raman 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 ?D?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 our spectrometers with linear CCDs, the slits 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-Raman 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-Raman Spectrometer is a great option for low-light level Raman spectroscopy. 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 Programming
The QE65000-Raman 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 spectrometers integration period. The spectrometers 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.
Plug-and-Play USB Operation
The QE65000-Raman interfaces to a computer via USB 2.0 or RS-232 serial port. Data unique to each spectrometer are programmed into a memory chip on the QE65000; our SpectraSuite Spectroscopy Operating Software reads these values for easy setup and hot swapping among computers, whether they run on Linux, Mac or Windows operating systems.
QE65000-Raman Configuration
The QE65000-Raman is preconfigured with the following, along with SpectraSuite spectrometer operating software, probe (RIP-Probe-785), laser (Laser-785-IP), and our Annual Service Package (ASP) to extend the warranty from 1 year to 2 years:
