Translucent materials primarily used for lamp shades and lamp lenses manifest, in addition to high transparency, the property of converting the regular behavior of light to a diffuse behavior. This characteristic can be “taught” to transparent plastics by the addition of light‐scattering functional additives or “diffusers”. The present article examines the requirements concerning diameter and concentration made on the functional additive barium sulfate when used as a diffuser in polycarbonate, and the associated optical material properties.
