    摘要： The invention relates to wafer-level manufacturing of optical devices such as modules comprising micro-lenses. In one aspect, passive optical components such as truncated lenses are manufactured by providing a substrate on which a multitude of precursor optical structures is present; and removing material from each of said multitude of precursor optical structures. Another aspect comprises a method for manufacturing a device comprising a set of at least two passive optical components, said method comprising the steps of using a tool obtained by carrying out the steps of manufacturing a precursor tool having a replication surface; and modifying said replication surface by removing material from said precursor tool. An yet another aspect comprises a method for manufacturing a device comprising a set of at least two passive optical components, wherein the method comprises the step of using a master comprising a replication surface comprising, for each of said passive optical components, a first portion describing a shape corresponding to the shape of at least a portion of the respective passive optical component, wherein the master comprises, in addition, at least one protruding portion protruding from at least one of said first portions of said replication surfaces.

    摘要： The method for manufacturing optical light guide elements comprises a) providing a plurality of initial bars, each initial bar extending along a respective initial-bar direction from a first bar end to a second bar end and having a first side face extending from the first bar end to the second bar end, the first side face being reflective; b) positioning the initial bars in a row with their respective initial-bar directions aligned parallel to each other and with their respective first surfaces facing towards a neighboring one of the initial bars; c) fixing the plurality of initial bars with respect to each other in the position achieved in step b) to obtain a bar arrangement. The method further comprises at least one of the following steps d), d′), d″): d) segmenting the bar arrangement into bars referred to as prism bars each of which comprises a portion of at least two different ones of the plurality of initial bars, by conducting a plurality of cuts through the bar arrangement; in particular wherein the cuts are parallel cuts; d′) segmenting the bar arrangement into bars referred to as prism bars by separating the bar arrangement into parts along cut lines, wherein the cut lines are at an angle with the initial-bar directions; d″) segmenting the bar arrangement into bars referred to as prism bars by separating the bar arrangement into sections by creating cut faces which are at an angle with respect to the initial-bar directions. And the method further comprises e) segmenting the prism bars into parts.

    摘要： Optical stack assemblies and fabrication techniques thereof. The optical stack assembly includes first and second sub-assemblies, each of which include a substrate and a sub-structure fixed to the respective substrate. Each sub-structures includes a respective first edge feature and a respective second edge feature that project away from the substrate of that sub-structure, each second edge feature being disposed laterally closer to an outer periphery of the respective sub-structure than the first edge feature of the same sub-structure. The first edge feature of the first sub-structure is in direct contact with the first edge feature of the second sub¬structure, while the second edge feature of the first sub-structure and the second edge feature of the second sub-structure are attached to one another by adhesive. At least one of the first or second sub-structures includes an optical element on a same side of the sub-structure as the first and second edge features of that sub-structure. The optical element stack assembly further includes a spacer laterally surrounding, and moulded to, the first and second sub-assemblies.
