Spectrometer optics is the process of measuring light intensity by separating light by wavelength using a spectrometer. Spectrometers have a wide range of applications, from studying distant galaxies to detecting cancer. A basic spectrometer design consists of an entrance slit, a diffraction grating or prism, and a detector, with routing optics used to direct light within the spectrometer. The optical system separates light into its constituent wavelengths, creating a spectra, and the detector measures intensity as a function of wavelength. Various types of spectrometer designs are available, each with specific requirements depending on the application and wavelength of light to be analyzed.
