Planar gratings are mainly used for spectrum analysis and light wavelength measurement. It is an optical device composed of a large number of parallel slits of equal width and equal distance. There are many types of gratings. The commonly used grating is made by engraving a large number of parallel notches on the glass. The nicks are divided into opaque parts, and the smooth part between the two nicks can transmit light. The exquisite grating produced by our company has thousands to tens of thousands of nicks within 1CM width, and the light passes through the grating. The resulting spectrum is the result of single-slit diffraction and multi-slit interference.
