QE65 Pro latest research-grade fiber optic spectrometer
QE65pro is Ocean Optics' latest research-grade fiber optic spectrometer, with higher sensitivity and lower stray light, and TEC second-stage cooling providing higher stability, giving it advantages in weak-light detection such as fluorescence, Raman, and DNA sequencing. ; Detector cooling can control the detector temperature to 40°C below ambient, giving the spectrometer higher wavelength and intensity stability. The trigger function provides precise time-synchronization control for triggering peripheral devices or for triggering the spectrometer. Replaceable slit design allows users to conveniently and easily replace the slit themselves. And the variety of selectable gratings has been expanded. ; Optical design optimization and improvement; To meet customers' needs for high cost-performance and high flexibility. Our QE65pro has the following features: ; New grating options to meet customers' wavelength, spectral range, and stray light control requirements. ; New optical component design to improve light efficiency and sensitivity. ; SMA905 and replaceable slit design, meeting the convenience of slit replacement and good stability. ; New optical bench design to provide more stable wavelength thermal stability. ; Back-illuminated area array CCD; The core of the QE65pro is the Hamamatsu FFT-CCD detector, which has extremely high quantum efficiency (peak 90%) and extremely low etalon effect. Unlike linear array CCDs, the QE65pro allows area array CCD pixels to be binned, allowing an entire column to be binned vertically as a single pixel, which can greatly improve sensitivity and signal-to-noise ratio (>1000:1) and increase processing speed. ; Moreover, TEC cooling (down to -15°C) gives the detector lower noise, more favorable for weak-light detection, and the integration time can be continuously adjusted from 8ms to 15 minutes, without distortion or deformation of the spectrum. ; Ideal choice for Raman spectroscopy; The QE65pro is the ideal choice for fluorescence and Raman spectroscopy measurements, especially for modular Raman fiber optic spectrometer configurations. For Raman measurements, we offer a 900 lines/mm grating (#H36), with a blaze wavelength of 500nm, providing good spectral response for both 532nm and 785nm laser Raman. ; Raman experiment setup: ; A modular Raman system composed of the QE65pro, a Raman fiber optic probe, and a laser. One end of the bifurcated fiber connects to the 785nm laser, and the other end connects to the spectrometer. It can be used for measuring solid and powder samples, and liquid samples can also be placed in a cuvette for measurement.
