② height detection device 223 for detecting whether the height of the material is qualified

The grating is also known as a diffraction grating. An optical element that disperses (decomposes) light into spectra by using the principle of multi-slit diffraction. It is a plane glass or metal sheet with a large number of parallel equal-width equidistant slits (scribed lines). The number of slits of the grating is large, typically tens to thousands of slits per millimeter. Monochromatic parallel light forms a pattern with wide dark fringes and fine bright fringes, called spectral lines, by diffraction of each slit of the grating and interference between slits. The positions of the spectral lines are different with the wavelength, and after the polychromatic light passes through the grating, the spectral lines with different wavelengths appear at different positions to form a spectrum. The formation of a spectrum of light by the grating is a common result of single slit diffraction and multi-slit interference.
