Figure 2-2 (a murb) shows the scattering effect of parallel light passing through silicone particles with diameters of 2 μ m and 3 μ m,
For the light diffusion films embossed on different surfaces, the haze increases to different degrees. The haze of the diffusion film of the cylindrical lens array increases rapidly, while that of the microlens array increases slowly.
