Abstract
An anti-reflective lens comprises a lens substrate and an anti-reflective layer formed on at least one surface of the lens substrate. The anti-reflective layer comprises a plurality of nano-structures spaced from each other. The plurality of nano-structures protrudes from the at least one surface of the lens substrate to form a compound-eye array. The anti-reflective layer is made of sol-gel composition. The disclosure also provides a method for manufacturing an anti-reflective lens.
Claims10
A method for manufacturing an anti-reflective lens, comprising:
- providing a sol-gel composition, a lens substrate, and at least one template, wherein each of the at least one template comprises a plurality of nano-patterns spaced from each other, the at least one template corresponds to at least one surface of the lens substrate, the plurality of nano-patterns is recessed from a surface of each of the least one template facing the lens substrate;
- coating the sol-gel composition on the at least one surface of the lens substrate, and pressing the at least one template on the least one surface of the lens substrate to cause the sol-gel composition to fully infill the plurality of nano-patterns;
- heating and curing the sol-gel composition coated on the at least one surface of the lens substrate, thereby forming an anti-reflective layer combined with the lens substrate, wherein the anti-reflective layer comprises a plurality of nano-structures corresponding to the plurality of nano-patterns, the plurality of nano-structures protrudes from the at least one surface of the lens substrate to form a compound-eye array;
- and
- removing the template.
