In optics, a diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions (i.e., different diffraction angles). The emerging coloration is a form of structural coloration. The directions or diffraction angles of these beams depend on the wave (light) incident angle to the diffraction grating, the spacing or distance be… WebThe grating pattern is created using either chrome deposition on a glass scale or laser written lines on a metal tape scale. A 20µm pitch diffraction pattern (10µm line, 10µm space, etc.) is most commonly utilized, though some products use 40µm pitch diffraction pattern (20µm line, 20µm space, etc.). ionic compounds are hydrophilic
