Grating is divided into many kinds of 3D grating, grating size safety grating, copy grating. Breath grating, reflection grating through. A diffraction grating. Are basically a series of parallel slits of equal width and spacing. We call it transmission grating. Some gratings need special coating treatment. According to this Yin and Yang effect, it evolves. More graphic mirrors, called reflection gratings, are simply like a flashlight projected against your finger onto an opposite wall, and you see patterns but only one is a low light and one is a macro light made as if in. Engraving on hair, the process is different. The earliest gratings were made in 1821 by the German scientist J. Fraunhofer using thin wire wound in close rows on two parallel fine screws. It is called "grating" because of its shape like a fence. The grating uses a precision engraving machine. On a piece of glass or metal. The grating is a grating spectrograph. There are many kinds of core components. According to the use of light penetration, emission or reflection into transmission grating reflection grating. Reflective gratings are more widely used and divided into flat according to their shapes. Surface grating and concave grating. In addition, there are holographic grating orthogonal grating phase grating show off grating staircase grating.
