So we are developing a plastic case, where we want light to be diffused through the case. The light is kept 2-3 mm away from the inside wall. I wanted to know what thicknesses allow passage of light, and also what colors allow better diffusion. I have seen a couple of products which are in White. But otherwise there is usually a light pipe for the diffusion.
Material most likely will be ABS+PC or just ABS. presently design is 1mm. we are thinking that particular area reduce thickness a bit and keep a provision for a cylinder to block light from diffusing to other areas. Any idea on what mix would be the best? or if color will also affect the diffusion. I cant recollect any black abs part which diffuses light. Only white I have seen.
