A polychromator is an optical device used to separate and analyze light into its component wavelengths or colors. It works by dispersing incoming light into a spectrum, which can then be measured or analyzed for various applications in fields such as spectroscopy, astronomy, and metrology. Polychromators typically utilize diffraction gratings, prisms, or filters to achieve this dispersion.
