METHOD AND KIT FOR FORMING PLASTIC LENSES FROM MOLDS FORMED ON SURFACE WITH VARIED WETTABILITY

摘要

This disclosure provides a monolithic mold including a plurality of lens forming features that can be used to simultaneously form a plurality of lenses with different sizes and shapes. The mold can be formed by disposing a polymeric material around a plurality of physical objects with different shapes and sized. A method of forming the mold includes providing a substrate that has a surface with regions of low and high wettability. Water is deposited on the surface such that water droplets are formed with different contact angles. The mold is formed around the droplets.

主权项

1. A kit comprising:
a monolithic mold having a first surface and a second surface, the mold enclosing a volume of a mold material between the first and the second surface, the mold including a plurality of lens forming features open to the first surface and extending through the volume of the mold material toward the second surface, wherein a cross-section of at least one of the plurality of lens forming features in a plane perpendicular to the first surface includes a curve, wherein the at least one lens forming feature is undercut such that a minimum spacing between opposing sides of the curve at a first location adjacent to the first surface is less than the minimum spacing between opposing sides of the curve at a second location between the first location and the second surface of the mold; and an amount of a lens forming polymer sufficient to fill the plurality of lens forming features.
