The QE Pro is a high sensitivity spectrometer with low stray light performance. It is ideal for a wide range of low light level applications such as fluorescence, DNA sequencing and Raman analysis.

Although custom QE Pro options are available, you also can choose from among various models -- including several new options -- that are preconfigured for common applications and wavelengths:

  • Absorbance 
  • Fluorescence
  • New! General-purpose UV-Vis (200-775 nm)
  • New! General-purpose Vis-NIR (350-925 nm)
  • New! Extended-range (200-950 nm)
  • New! Raman (w/785 nm excitation)

The sensitivity and large dynamic range of the QE Pro combine to make it the highest-performance modular spectrometer in its class. Key features include advanced optoelectronics and thermoelectric cooling to provide thermal stability, and onboard spectral buffering to ensure data integrity at high collection rates.



  • New wavelength-specific preconfigured models -- New QE Pro versions for UV-Vis, Vis-NIR and XR (extended-range) measurements (choose Select Model above for details)

  • Application-specific preconfigured models -- QE Pro versions for absorbance, fluorescence and Raman

  • 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

  • Buffering -- up to 15,000 spectra
