What is a Diffraction grating?
A diffraction grating is an optical component with a surface engraved with regular grooves or grid structures, used to separate light into specific wavelengths. It operates based on the principles of diffraction and interference, enabling light to be split into its spectral components. Diffraction gratings are used in spectrometers, lasers, telecommunications, and optical analysis instruments. They are indispensable for precise spectral measurements and wavelength selection. There are two main types: reflective and transmissive, chosen according to the application.
Application of Diffraction grating
✅Spectroscopic analysis
Diffraction gratings are used to split light into spectra to measure wavelengths for chemical composition analysis.
✅Optical telecommunications
Used in wavelength-division multiplexing systems to separate or combine optical signals of different wavelengths.
✅Laser technology
Applied for precise control and adjustment of laser wavelengths.
