The QE Pro is a high sensitivity spectrometer with low stray light performance. It is ideal for a wide range of low light level applications such as fluorescence, DNA sequencing and Raman analysis. Custom and preconfigured absorbance and fluorescence options are available.
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, spectral buffering ensures data integrity at high collection rates; advanced optoelectronics and thermoelectric cooling combine to provide thermal stability over long-term measurements.
The QE Pro-FL is a preconfigured option for fluorescence. It has a wide-range grating and 200 µm slit.
