<p>The present invention has the object to provide an optical element having an antireflection film formed on a plastic substrate, the advantages of which are that the reflectance of the antireflection film is low while the transmittance thereof is high, that the impact resistance, the adhesiveness, the heat resistance, the abrasion resistance and the alkali resistance on the plastic substrate are superior, and that the productivity is good.
€ƒ€ƒ€ƒ This object is achieved with an optical element having an antireflection film, which has a plastic substrate and an antireflection film formed thereon through vacuum evaporation, wherein at least one layer of the antireflection film is a hybrid layer made of an inorganic substance and an organic substance.</p> |
