Technical Data
QE Pro is a high sensitivity spectrometer with low stray light performance. Ideal for a variety of low-light applications, such as fluorescence, DNA sequencing and Raman analysis, it is available in customized versions as well as absorbance and fluorescence preconfigured versions.
QE Pro combines sensitivity and large dynamic range, making it an excellent micro-spectrometer in its class. QE Pro can perform absorption, reflection, fluorescence and Raman measurements. For advanced measurements, spectral caching ensures the integrity of their data. QE Pro combines advanced photoelectric technology and thermoelectric cooling technology to provide thermal stability in long-term measurements.
