Abstract: Optical modules are made using customizable spacers to reduce variations in the focal lengths of the optical channels, to reduce the occurrence of tilt of the optical channels, and/or prevent adhesive from migrating to active portions of an image sensor.

Abstract: The present disclosure describes methods of attaching surfaces together. In one aspect, a method includes depositing a first adhesive onto a first surface of a first item, the first adhesive forming a pattern that at least partially surrounds a region of the first surface where there is no first adhesive. A second adhesive is jetted onto the region of the first surface, wherein the second adhesive has a viscosity lower than a viscosity of the first adhesive. The first surface of the first item and a second surface of a second item are brought into contact with one another. The method also includes curing the first and second adhesives. While the methods can be particularly suitable for manufacturing optical light guide elements, the methods also can be used in other contexts and applications as well.

Abstract: Optoelectronic modules for light emitting and/or light sensing include optical assemblies and active optoelectronic components. An optical assembly and a corresponding optoelectronic component can be aligned. The optoelectronic modules can include multiple optical assemblies and active optoelectronic components. Multiple optical assemblies and corresponding active optoelectronic components can be aligned independently of each other in various implementations of optoelectronic modules that include alignment features and optical assembly barrels.

Abstract: Optical assemblies include a stack of optical elements each of which has one or more alignment features. Each alignment feature traces a respective curve along a surface of one of the optical elements. The alignment feature(s) of one optical element fit within the alignment feature(s) of the other. In some cases, the alignment features can help establish more precise lateral alignment of the optical elements.
