MIRROR COATED LENS MADE OF PLASTIC

摘要

PROBLEM TO BE SOLVED: To provide mirror coated lenses which are made of plastic, are enhanced in the antireflection effect of the concave surfaces of the lenses and are lessened in reflection without impairing the reflection increasing effect of the convex surfaces of the lenses. SOLUTION: Function films of the lenses which are provided with function films on the convex surfaces of a plastic substrate for the lenses and of which the convex surfaces have the reflection increasing effect and the concave surfaces have the antireflection effect are the films laminated with a first layer to a sixth layer successively from the surface of the plastic substrate. The respective layers consist of specified material and have specific film thicknesses and transmittance.
