ABSTRACT:
An apparatus for making microlens molds and microlens array molds is described which utilizes a forming element having a rotating half radius diamond cutting member. A substrate is alignably arranged with the diamond cutting member so that the cutting member can mill a mold cavity in the substrate. The apparatus can be used to make high sag lens molds with high accuracy and a nearly 100% fill factor.
