  • Apparatus for forming a microlens array mold
    Patent number: 6908266
    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.
    Type: Grant

  • Microlens array mold
    Patent number: 6799963
    Abstract: A method for making a double-sided microlens mold and microlens array mold 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 turnable 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.

  • Apparatus and method for molding glass optical elements
    Publication number: 20030145626
    Abstract: A method and apparatus are taught for molding glass lens elements from glass preforms. A glass preform is placed on a first mold surface of a first mold element which resides in a first sleeve segment. The temperature of the glass preform, the first mold element, the first sleeve segment, a second mold element, and a second sleeve segment are elevated to at least the glass transition temperature of the glass preform, the second mold element residing in the second sleeve segment. The second mold element and second sleeve segment are moved toward the first mold element and first sleeve segment to form a mold cavity, the mold cavity including a lens chamber and an annular channel projecting from the lens chamber. The glass preform is compressed in the mold cavity to form a glass lens element with the excess glass from the glass preform flowing into the annular channel.
