Acrylic diffuser plate, also known as PMMA diffusion plate/polycarbonate diffuser, is a material with light diffusivity in the PMMA (polymethyl methacrylate, alias acrylic, Yajiali, plexiglass) plate category, a material in the PS (polystyrene), PC (polycarbonate), PP (polypropylene) and other material diffusion plate category, and has the optical characteristics of high haze, high transmittance, high diffusivity and other plastic plates, It can effectively convert the point or line light source into a soft and uniform area light source. On the premise of achieving good light transmittance, it also has good light source dot matrix shielding property. It is an ideal optical material to solve the secondary light distribution of LED lighting products, and is the best light diffusion material for LED lighting products.
