Reflecting mirror for airplane

摘要

A large number of ring-like grooves having mutually different diameters are concentrically formed on the back of a planar transparent plastic plate to constitute a Fresnel lens having a concave lens function, a reflecting film is provided to the back so as to provide a convex mirror function to the surface of the transparent plastic plate, and a thin metal sheet is bonded to the reflecting film through an adhesive, thereby constituting a reflecting mirror for an airplane cabin.
