The biggest feature is the diffusion plate light cause great interference, regardless of the original design of the distribution curve is the number of degrees, as long as it makes a light beam through a diffuser plate angle becomes 160 ~ 176 °, so that from the side, the lamp board foggy foggy feeling layer, from this point may prove beam angle is 160 ~ 176 ° large the best proof, the greater the lower the beam angle of illumination, and some also produce filters, so that part of the wavelength can not penetrate cause color shift, such as the surface of the optical interferometric processing again (example: frosted, charge lines), the light transmittance due to geometrical optics of natural phenomena is low, so the base material used to make the refractive index of the diffuser plate should be used the lower the better, the lower the interference of light. Species diffusion plate classification according to the principle of optical diffusion plates were divided into two types, one is the beam angle will become a big one is to maintain the original angle to material classification, glass ,, polystyrene (PS), polycarbonate ester (PC), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), acrylic (PMMA), acrylic acid (MMA) .. .. and so the transparent polymeric material or a synthetic material may be manufactured as a diffusion material for different purposes. Species can be divided into gas diffusion plate diffusion plate, the sound diffusion plate, liquid diffusion plate, a light diffusion plate, scent diffusion plate, a light diffusion plate, a uniform dispersion of materials can Jufan molecules are collectively referred to as a diffuser plate. Gas diffusion plate -> generally used to reduce the sound generated by the air flow due to, for example: a car muffler. Sound diffuser plate -> General to eliminate the sound barrier and echo due to hard objects, such as: the concert hall walls or ceilings. Liquid diffusion plate -> generally used liquid into mist or smaller molecules uniformly distributed out, for example: a greenhouse with curtain. The scent diffusion plate -> General to eliminate or reduce the dispersion taste it, such as: gas mask canister or water filter canister of deodorant. Light diffusion plate -> General to prevent glare so get a comfortable visual environment, such as: a diffusion plate in front of a camera flash. Division I diffuser plate are: Chimei imported and domestic. Thickness: 1.5T, 2T Material: PS, PC, PMMA, PET have questions please call to discuss.
