CMS-2S High Reliability Fast Test Spectroradiometer System

Fast test spectroradiometer system is make up of CMS-2S fast spectroradiometer, integrating sphere, power supply, calibration system, etc. This system adopts the most advanced holographic concave diffraction grating and toshiba high performance linear CCD display detector. It can also achieve the millisecond measurement speed and the same test accuracy as the traditional mechanical spectroradiometer. It has the characteristics of fast test, convenient use, long life, high reliability and small volume etc.
