Edmund Optics offers a wide range of transmission and reflection diffraction gratings for ultraviolet (UV), visible, and infrared (IR) bands. During manufacturing, a single master grating is used to create its replicas. The type of grating is determined by the manufacturing process. Blazed diffraction gratings consist of a series of grooves that are formed by transferring the grating surface of a master grating made with precision diamond tools. Blazed diffraction gratings are used in applications that require high efficiency. Holographic diffraction gratings are produced using interference fringes generated by two laser beams. Holographic diffraction gratings are suitable for applications that seek to minimize stray light. For more details, please check the official Edmund Optics website via the link below.
basic information
A diffraction grating is an optical element used to separate light into its constituent wavelengths. Diffraction gratings are used in spectral analysis and are integrated into spectrophotometers and monochromators. The surface of a diffraction grating is treated with a series of closely spaced grooves formed by scribing or etching. Diffraction gratings function either by transmission or reflection. When light passes through or reflects off the grating surface, the individual grooves diffract the light, dispersing it into its constituent wavelengths. When using a diffraction grating, special care is required in handling due to the soft coating applied to its surface.
