👉 A monochromator is a device that converts light into an electromagnetic spectrum. It consists of a single object, such as a prism or a diffraction grating, which can be used to separate and amplify light. The principle behind a monochromator is based on the phenomenon of interference between different wavelengths of light, allowing them to be separated and combined in a certain way. This allows for precise control over the wavelength of light and enables the creation of various optical instruments such as spectroph
