CMS-3000S Fast Spectrometer system adopts the most advanced holographic concave diffraction grating and high performance electronic shutter control linear CCD display detector. It can realize super low stray light and wide linearity dynamic measuring range. It has high repeatability and stability, and can also achieve the millisecond measurement speed and the same test precision as the traditional mechanical spectrometer. It's mainly applied to the quality control and quantity production as well as the lab research equipment.
