QE Pro

The sensitivity and large dynamic range of the QE Pro combine to make it the highest-performance miniature spectrometer in its class. Absorption, reflectance, fluorescence and Raman measurements all benefit from the superior performance of the QE Pro. For advanced measurements, a 15,000 spectra buffer ensures data integrity at high collection rates and an advanced optical design and thermoelectric cooler combine to provide thermal stability over long-term measurements. Whether for high speed or wide concentration range measurements, the QE Pro brings exceptional performance to your lab or process application.

Features

Wide Dynamic Range   
Low-noise electronics and an 18 bit A/D converter double the QE Pro’s dynamic range and increase the sensitivity by a factor of two compared to typical back-thinned CCD array miniature spectrometers. These enhancements drive applications benefits such as improved lower limit of detection for both absorption and fluorescence measurements and enable measurements over a wider concentration range.   
   
Buffering for Fast Measurements   
To support fast, and full-spectrum data acquisition, the onboard buffer stores up to 15,000 spectra. This maintains data integrity by buffering time stamped spectra for USB communications. Buffering enables full-spectrum kinetics measurements to be performed every 8 milliseconds or 125 measurements per second.   
   
Reliable Performance   
Thermoelectric cooling (TEC) precisely controls the temperature of the detector. Cooling the detector dramatically reduces the effect of thermal noise and improves overall the stability of the detector for lengthy measurements. The TEC in the QE Pro holds data stability to 4 dark counts over a 60 °C ambient temperature range, giving you the highest quality data. This stability performance makes the QE Pro ideal for demanding online and at-line quality control measurements susceptible to temperature changes.   
   
Kinematic mounts are used to position the optical elements of the QE Pro to increase accuracy and reliability. New RS-232 communication protocols allow the QE Pro firmware to be updated in the field, ensuring you have the most up-to-date product.
