QE Pro (Custom)

High-sensitivity Spectrometer for Low Light Level Applications

Please contact us online for more information about ordering this product.

High Performance Spectroscopy

The QE Pro is a high-sensitivity spectrometer ideal for low light level applications such as fluorescence, DNA sequencing and Raman analysis. The QE Pro’s back thinned CCD detector has high quantum efficiency and its robust design yields great signal to noise performance and stability. An optional internal shutter is available for effective management of dark measurements.


For more information, view:

  • Portable – small footprint, high performance fiber optic spectrometer
  • Sensitive – high quantum efficiency detector
  • Powerful – signal-to-noise ratio >1000:1
  • Stable – cooled detector allows low light detection and prevents spectral distortion
  • Configurable – interchangeable slits, internal shutter (optional) and various gratings
