Abstract: A method of manufacturing a master for use in a wafer-scale replication process is disclosed. The method comprises at least one step of forming a layer of photoresist on a substrate and exposing the layer of photoresist to a radiation pattern to form at least one patterned layer. The method also comprises a step of developing the at least one patterned layer to provide one or more structures defining the master. In an embodiment, the at least one step of forming the layer of photoresist comprises a process of dry film lamination.

Abstract: A method for producing a plurality of optical prisms comprises: providing at least one manufacturing intermediate; and dividing the at least one manufacturing intermediate into a plurality of individual triangular prisms. The manufacturing intermediate comprises a main body in the form of a triangular prism having three rectangular surfaces and two triangular surfaces. The main body is formed from a light-transmitting material. A layer of opaque material is provided on two of the three rectangular surfaces of the main body, the layer of opaque material having a plurality of axially spaced apertures on each of the two of the three rectangular surfaces, each one of the apertures on one of the two surfaces being disposed at substantially the same axial position as one of the apertures on the other one of the two surfaces. The at least one manufacturing intermediate is divided into a plurality of individual triangular prisms such that each individual triangular prism has one of the apertures on each of two sides thereof.

Abstract: Manufacturing optoelectronic modules includes supporting a printed circuit board substrate (27) on a first vacuum injection tool (24). The printed circuit board substrate (27) has at least one optoelectronic component mounted thereon and has a solder mask (40) on a surface (46) facing away from the first vacuum injection tool (24). The method includes causing the first vacuum injection tool (24) and a second vacuum injection tool (22) to be brought closer to one another such that a surface (46) of the second vacuum injection tool (22) is in contact with the solder mask (40). Subsequently, a first epoxy (100, 20) is provided, using a vacuum injection technique, in spaces (104) between the upper tool (22) and the solder mask (40).

Abstract: A method of making optical diffuser elements (20) includes providing a substrate (100) composed of a polymer material and having openings (102) therein. An optical diffuser material (110) is dispensed into the openings (102), and the optical diffuser material (110) is hardened to form a sheet (200) composed of regions of the optical diffuser material (110) surrounded laterally by the polymer material. The method includes separating the sheet (200) into multiple optical diffuser elements (30) that retain their mechanical stability and optical properties when subjected to a reflow process.
