Anti-reflection film for synthetic resin optical elements
摘要:
An anti-reflective film for synthetic resin optical parts of elements. The film comprises a first SiO layer, a second SiO.sub.2 layer, a third CeO.sub.2 layer and a fourth SiO.sub.2 layer, each layer having a particular optical thickness at a wavelength of .lambda.=400-700 nm.
