QE65Pro cooled CCD Spectrometer

Ocean Optics QE65Pro or QE65000 high quantum efficiency, backthinned CCD array

QE65Pro...  now with user interchangeable slits in bot FC and SMA!

The Ocean Optics QE65Pro is our top-of-the-line back-thinned CCD spectrometer. It has a highly sensitive detector with high quantum efficiency, cooling to 0 degrees C, on onboard buffer that holds up to 15,000 spectra for fast data acquisition and for the first time, user interchangeable slits!  You can even switch from SMA to FC style connectors. The QE65Pro achieves up to 90% quantum efficiency with high signal-to-noise and excellent signal processing speed.

User-configured and Application-ready Options
Both the QE65000 and Maya systems can be optimized for your application needs by specifying various optical bench accessories and grating options. In addition, the QE65000 is available in three applicationready models:
- QE65Pro-ABS
Preconfigured for absorbance measurements and includes an
HC1-QE grating (starting at 200 nm), an OFLV-QE-200 order sorting filter
and a 10 μm entrance slit. Spectrometer Operating Software and our
Annual Service Package are also included.
- QE65Pro-FL
Preconfigured for fluorescence measurements and includes an HC1-QE
grating (starting at 350 nm), OFLV-QE-350 and a 200 μm entrance slit.
Spectrometer Operating Software and our Annual Service Package are
also included.
- QE65Pro-RAMAN
Preconfigured for low light-level Raman spectroscopy and includes an H6 grating (starting at 780 nm) and a 50 μm entrance slit. Operating
software and service packages are available separately.

Trade-in your old Ocean Optics for up to a $3,000 credit towards a new QE65Pro!

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.


Reliable Performance

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.
