Description
The QE Pro is a high sensitivity spectrometer with low stray light performance. It is ideal for a wide range of general and low light level applications including absorbance, fluorescence, DNA sequencing and Raman analysis. Custom and preconfigured options are available.
The sensitivity and large dynamic range of the QE Pro combine to make it the highest-performance miniature 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.
Preconfigured for Vis-NIR measurements – preset for 350-925 nm, with 10 µm slit and order sorting filter
Sensitive – high quantum efficiency detector
Powerful – signal-to-noise ratio >1000:1
Stable – cooled detector allows long integration times for low light level detection and prevents spectral distortion
Buffering – up to 15,000 spectra
