The QE65 Pro is the result of feedback from customers like you who appreciate high performance at a reasonable price and appreciate the flexibility of our modular approach to miniature spectroscopy. Consider some of the enhancements we’ve made to the QE65 Pro:
- Availability of new gratings, selected for their optimal wavelength range and stray light performance characteristics
- New optical bench components that more efficiently manipulate light for greater throughput and higher sensitivity
- SMA 905 connector assembly with replaceable slit design for added convenience and excellent repeatability
- Changes to the optical bench and its components that promote excellent spectrometer wavelength thermal stability
Back-thinned Detector
At the heart of the QE65 Pro is a Hamamatsu FFT-CCD detector distinguished by its high quantum efficiency (90% maximum) and low etalon characteristics. Unlike linear CCDs, the 2D area detector in the QE65 Pro allows us to 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.
What’s more, the TE-cooled (down to -15 °C) detector has low noise and low dark signal, which enables low-light-level detection and long integration times -- from 8 milliseconds to 15 minutes, with virtually no spectral distortion.
Ideal For Raman
QE65 Pro is a great choice for fluorescence and low light level applications and is particularly well suited for modular Raman spectroscopy. For Raman, we offer a 900 mm-1 grating (#H36) that is blazed at 500 nm and has good response at the 532 and 785 nm laser illumination wavelengths typical of Raman.
In this setup, the QE65 Pro anchors a modular, probe-based Raman system. You’ll note a bifurcated optical probe with one leg coupled to a 785 nm laser (in middle of photo) and the other to the spectrometer. Cuvette-based Raman analysis is also possible.
