Entrance SlitDiffraction Grating Or PrismDetectorRouting OpticsHigher Order FiltersThe optical detector records the intensity of the light that reaches it as a function of its wavelength. Spectrometer detectors consist of a row of light sensitive pixels, each of which corresponds to a particular wavelength. Each pixel will generate an electrical signal of intensity proportional to how much light falls on it. Charged-coupled devic...See more on ossila Avantes
