The QE Pro Series are high sensitivity spectrometers 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.
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.

• Highest Sensitivity: 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
