Diffraction Gratings

Diffraction Gratings are precision optical components used to disperse light into its component wavelengths for spectral analysis. These gratings consist of a surface with a series of closely spaced lines or grooves that diffract incoming light at specific angles depending on wavelength, enabling separation and measurement of spectral bands. Available in transmission or reflection formats, diffraction gratings are made from materials like glass or quartz and are often coated for enhanced optical performance. They are widely used in laboratories, research institutions, and industrial applications involving spectroscopy, photonics, and laser systems.
