Abstract
Optical quality molds and mold inserts include an optically flat substrate, a layer of material applied to the substrate and one or more depressions in a predetermined pattern formed in the layer of material applied to the substrate. The depth of the depressions are precisely determined by the thickness of the layer applied to the substrate. By contacting the mold with resin in a fluid state, a component is fabricated having microfeatures formed monolithically thereon.
