DQPro is a deep-cooled miniature optical fiber spectrometer based on symmetrical CT optical path design, with compact structure design and configurable spectral range. It adopts N.A0.11, with high resolution, up to 0.1nm; Low stray light,~5 ‰. Equipped with back-illumination and deep cooling CCD, the cooling temperature can reach - 20 ℃. With good spectral response stability and reproducibility, it is suitable for laser measurement, plasma emission spectrum measurement, color measurement, absorbance measurement, Raman measurement and other industrial field measurements. It is a scientific research and high-performance optical fiber spectrometer.
◆ Based on the traditional CT optical path design, the front focal length is 100mm, and the rear focal length is 100mm
◆ NA.0.11 numerical aperture is adopted, with high resolution, and the best resolution is~0.1nm
◆ Platform-based design, can be configured with 300g/l-2400g/l gratings of various specifications
◆ Equipped with deep-cooled CCD, the cooling temperature can reach - 20 ℃, with extremely low readout dark noise and good stability
◆ key-SMA905 design, which can be adapted to mult
