What is a monochromator and how does it work?

Date:2023-01-07
A monochromator is an optical device which is used to separate out light of various wavelengths. It does this by passing the light through a diffraction grating, which separates out the light into its component wavelengths by bending the light into different directions. The light is then focused on a detector, which measures the intensity of the light at each wavelength. This device is used in many applications, from spectroscopy to fiber optics.
