发明名称 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.
