No ghost line and companion line will be generated during work, which is the most popular among users. b. There are no defects such as microscopic irregularities or burrs that mark the groove of the grating, so the stray light is much smaller than that of the grating. c. The diffraction efficiency is low. The groove shape of the holographic grating is usually an approximate sinusoidal waveform. This groove shape does not have blaze conditions and has no obvious blaze characteristics. It is said that the holographic grating using the "ion etching" technology has greatly improved the diffraction efficiency of the grating. d. High resolution. As the holographic technology greatly increases the total number of grating lines, the dispersion rate and resolution are also greatly improved. e. Appropriately changing the production conditions can produce aberration-free holographic gratings. f. Any size holographic grating can be made. g. Short manufacturing cycle.
