Light diffuser acrylic sheet, the PMMA diffuser has the optical characteristics of plastic sheets such as high haze, high light transmittance, high diffusivity, etc., which can effectively transform point or line light sources into soft and uniform surface light sources, under the premise of achieving good light transmittance , At the same time, it has a good light source lattice shielding property. It is an ideal optical material to solve the secondary light distribution of LED lighting products, and it is the best light diffusion material for LED lighting products.
Our components set new benchmarks for performance in key metrics such as transmission efficiency for a given level of diffusionor hiding power, beating holographic, surface relief and bulk diffuser techniques PMMA light diffusion sheet.
