Method of manufacturing a microlens and a microlens array

摘要

A method for making microlens and microlens array is described which utilizes a spinning half radius diamond cutting member operated in a plunge cut in a technique similar to milling to cut the optical surface into a diamond tumable material. The method can be used to make high sag lens molds with high accuracy. Microlens array molds can be made with a high degree of uniformity and a nearly 100% fill factor.
