Wide dynamic range
Due to the low noise electronic part and 18-bit A/D converter, the dynamic range of QE Pro is twice that of the common back-illuminated thin CCD array micro spectrometer, and its sensitivity is also improved by 2 times. These improvements can bring many benefits for practical applications, such as lower detection limits of absorbance or fluorescence detection, and detection in a wider concentration range.
 
Buffer for fast detection
In order to better support fast full-spectrum data acquisition, we have increased the onboard buffer so that it can now store 15,000 spectra, so that under the condition of USB communication, we can ensure data integrity by buffering time tag spectra. Therefore, you can obtain 8ms/sheet or 125 sheets/second full spectrum dynamic data when carrying out full spectrum dynamic detection.
 
Reliable performance
Thermoelectric refrigeration can accurately control the temperature of the detector, greatly reduce the influence of thermal noise, thus improving the overall stability of the detector during long-term detection. QE Pro is equipped with thermoelectric refrigeration devices to keep dark noise stable at 4 counts when room temperature changes above 60 degrees, thus giving you high-quality data. The high stability of QE Pro makes it very suitable for on-line or off-line quality control inspection which is very demanding and sensitive to temperature changes.
 
The dynamic assembly of optical devices used in positioning QE Pro greatly improves the accuracy and reliability of QE Pro. At the same time, the new RS-232 communication protocol allows QE Pro's Firmware to be upgraded on site, so that you can always have new products with new functions.
