What is a Diffraction grating?
A diffraction grating is an optical element made by forming fine grooves at regular intervals on a glass substrate. When light is applied to the diffraction grating, the effect of the groove causes a diffraction phenomenon of the light, so that the incident light can be divided according to the wavelength. There are various types such as transmissive type, reflective type, and blazed type. Since each has a slightly different structure, the spectral performance is also different. Since a diffraction grating can extract light of a specific wavelength, it is used in spectroscopes such as monochrome meters that emit light of a single wavelength and polychromometers that emit light of a certain wavelength.
Application of Diffraction grating
The diffraction grating has fine grooves on the surface, and has the property of splitting the incident light for each wavelength. This property is used in devices that control the wavelength of light. For example, it is used in spectroscopes such as monochromators that emit single wavelengths and polychromators that emit wavelengths of a certain width. It is also used in spectrophotometers for astronomical observations, various spectroscopic analyzers in the field of natural science, manufacturing equipment for pharmaceuticals and chemicals, and quality control equipment.
