QE Pro High Performance Spectrometer
The sensitivity and large dynamic range of the Ocean Optics 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.
At a Glance:
- Wavelength range: Configurations support the range of 185 – 1100 nm
- User interchangeable entrance slits
- Optical resolution: 0.14 - 7.7 nm (FWHM) depending on configuration
- Internal shutter (optional) for effective management of dark measurements
- System SNR: 1000:1
- A/D resolution: 18 bit
- Dynamic range: 85,000 (typical)
- Stray light: <0.08% at 600 nm; 0.4% at 435 nm
- Buffering: 15,000 spectra
- TEC: Cooling to -40 ºC below ambient -40 ºC to +50 ºC temperature limits
Wide Dynamic Range
Low-noise electronics and an 18 bit A/D converter double the QE Pro’s dynamic range and increase its sensitivity by a factor of two compared with typical back-thinned CCD array miniature spectrometers. These enhancements provide lower limits of detection for both absorption and fluorescence measurements and enable measurements over a wider concentration range.
Buffering for Fast Measurements
To support fast, 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.
The high-sensitivity QE Pro is a good option for measuring the Raman shift of aromatic hydrocarbons such as toluene.
Thermoelectric cooling (TEC) precisely controls the temperature of the detector. Cooling the detector dramatically reduces the effects 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.
