Details
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 spectrometers that preconfigured for common applications:
- Absorbance
- Fluorescence
- General-purpose UV-Vis (200-850 nm)
- General-purpose Vis-NIR (350-1000 nm)
- Extended-range (200-950 nm)
- Raman (w/785 nm excitation)
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.
Overview
- Multiple preconfigured models -- QE Pro versions for absorbance, fluorescence and Raman; and for UV-Vis, Vis-NIR and XR (extended-range) measurements
- 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
