20250026052 · 2025-01-23 ·

A method for reaction injection molding of a structured component is disclosed. The method includes (i) closing a mold in order to provide a cavity adapted to form the component, wherein the mold includes a negative shape of the component, (ii) injecting a reaction injection molding resin at a low packing pressure into the cavity in order to fill the cavity, (iii) curing the reaction injection molding resin in the cavity using UV-light through a transparency in the mold, (iv) opening the mold, and (v) demolding the cured component. Also, a corresponding component, apparatus and system are disclosed.

Molds and method of using the same for optical lenses
09751268 · 2017-09-05 · ·

The present invention encompasses, in part, a method and apparatus for lens casting in which two molds, preferably formed of plastic, are interconnected or joined together via a ring to form a mold cavity having substantially the same dimensions of the lens to be formed therein. The invention is further directed to compositions and methods used in lens casting. In a first implementation the invention includes a mold having a ring having an interior periphery; a front mold formed of a plastic and having a lens-forming surface, an edge circumscribing the lens-forming surface that is sized to be complementarily received within a portion of the interior periphery of the ring, and a base having dimensions greater than the interior periphery; and a rear mold formed of a plastic and having a lens-forming surface.

Nanograting sensor devices and fabrication methods thereof
20170199127 · 2017-07-13 ·

The present invention relates to nanograting sensor devices and fabrication methods thereof. The nanograting sensor device includes a light transmissive optical component comprising a plasmonic thin film with nanostructure patterns. The nanostructure has a smooth shape profile which can enhance the efficiency of plasmonic coupling and light transmission and increase the sensing ability. Methods of the present invention provide a means of fabricating such plasmonic thin film structures. The sensor described in the present invention utilizes the changes of the plasmonic resonances to detect analytes and/or determine the concentration of analytes at the plasmonic thin film surface or in the fluid near the plasmonic thin film surface.
