Abstract

See full text

A method for preparing a sapphire lens includes the following steps: sequentially forming an ink layer and a coating film layer on one surface of a large polymeric membrane; laser-cutting the obtained large polymeric membrane to form two or more small polymeric membranes that are as thick as the large polymeric membrane; laminating the surface of the small polymeric membrane that does not contain the ink layer and the coating film layer to one surface of a sapphire sheet, such that an adhesive layer is formed between the small polymeric membranes and the sapphire sheet, wherein the sapphire sheet has a thickness of 0.3 to 1.5 mm, and the polymeric membrane has a thickness of 0.02 to 0.2 mm; and pressing the obtained sheet material to remove bubbles, thereby obtaining a sapphire lens.
