Description

Technical Field

[0001] The utility model relates to the technical field of diffusion plates, in particular to a diffusion plate with good diffraction performance. Background Art

[0002] As we all know, a diffuser with good diffraction performance is an optical element that can effectively diffuse or evenly distribute light. Such diffusers are usually used in optical applications such as lighting, display, imaging or sensors. Their design purpose is to scatter the incident light evenly in all directions through the diffraction effect, rather than reflecting or refracting it in only one direction.

[0003] However, after leaving the factory, the existing diffuser plates with good diffraction performance are generally transported to a designated location by transportation equipment. However, the existing diffuser plates have no protective devices, and the surface of the diffuser plates is easily worn, which may cause damage to the diffuser plates, resulting in reduced use effect of the diffuser plates.
