<p>A method of preparing a plural-layer optical membrane for adhesion mounting on a support frame, such as a ring. The method is employed with such a membrane whose mounting side is formed with a first layer structure and an underlying layer structure. The method involves the selective removal, in the pattern of the ring on which the membrane is intended to be mounted, of a substantially matching shape in the first-mentioned layer structure, thus to expose a portion of the higher-adhesion-affinity underlying layer structure.</p> |
