Abstract
A method of fabricating an optical assembly includes positioning an optical structure between a first portion of a mold tool and a second portion of the mold tool and providing a transparent liquid optical material into a first cavity of the mold tool and into the second cavity of the mold tool while the optical structure is positioned between the first portion of the mold tool and the second portion of the mold tool. The first cavity is defined by the first portion of the mold tool and the second cavity is defined by the second portion of the mold tool. The liquid optical material is cured to form the optical assembly.
