A diffraction grating is a optical material or device that is usually designed to break up white light into the various colors of the visible spectrum.laze angles are used to concentrate a diffraction grating output on a certain band region of the light spectrum. This is done to obtain a maximum resolution in a particular band of light known as the Blaze wavelength.
This grating is a system of interlocking, perpendicular bars, it provides a smooth clean look ideal for architectural applications such as grilles, divers and screens. It is used in the same structural applications as its welded steel counterpart. It is offered in a range of spacing options from 7/16 to 1-3/16. Press-Locked grating is not recommended for rolling loads.
