How Does a Spectrometer Work? Principles Explained
Entrance SlitDiffraction Grating Or PrismDetectorRouting OpticsHigher Order FiltersLight enters the spectrometer via the entrance slit. Similarly to how the aperture size of a camera affects the brightness and resolution of its photos, the width of the spectrometer entrance slit determines both its ability to measure in low-light conditions and the maximum spectral resolution that you can achieve. These two characteristics must b...See more on ossila nih.gov
