TURBOMACHINE AUXILIARY LEAD-THROUGH DEVICE

摘要

A lens mold and methods of fabricating such a lens mold are disclosed. The lens mold has a pattern for forming an antireflection structure. With such a lens mold, a lens die can be fabricated with the antireflection structure integrally formed on the exterior thereof. Compared to the prior art, the lens mold allows a lens die to be fabricated directly with an antireflection structure integrally formed therewith in a more reliable manner without the risk of fractures, detachments or other defects. A method of fabricating a lens die is also disclosed.

主权项

1. A method of fabricating a lens mold, comprising:
providing a first mold having a surface with a portion resembling a lens surface; forming a pattern for forming an antireflection structure on the surface of the first mold and then forming a first separable layer on the surface of the first mold; and subjecting the surface of the first mold successively to adhesive filling, curing and separation, thereby forming a second mold with the pattern transferred thereto.
