Principles of Spectrometer Wavelength Meters
An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of over a specific portion of the, typically used in to identify materials. The variable measured is most often the of the light but could also, for instance, be the state. Each pixel will generate an electrical signal of intensity proportional to how much light falls on it. They enable scientists to investigate matter on a microscopic level, detecting the unique spectral lines produced when elements interact with light. Entrance slit (1), diffraction grating or prism (2), a detector (3), routing optics (4), higher order filters. When light passes through a sample, the molecules in the sample absorb some of it, and the rest passes through.
