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:
Image sensor modules include primary high-resolution imagers and secondary imagers. For example, an image sensor module may include a semiconductor chip including photosensitive regions defining, respectively, a primary camera and a secondary camera. The image sensor module may include an optical assembly that does not substantially obstruct the field-of-view of the secondary camera. Some modules include multiple secondary cameras that have a field-of-view at least as large as the field-of-view of the primary camera. Various features are described to facilitate acquisition of signals that can be used to calculate depth information.
Abstract:
The method for manufacturing a multitude of devices comprises: - providing a replication tool comprising a tool material; - conditioning the replication tool, wherein the conditioning comprises applying a treatment to the tool material, wherein the treatment comprises exposing the tool material to a conditioning material. And it further comprises, after the conditioning: - carrying out one or more replication processes, wherein in each of the one or more replication processes, one or more of the devices are produced from a replication material by replication using the replication tool. The treatment can comprise dimensionally changing the tool material by the exposure of the tool material to the conditioning material. Before carrying out the replication processes, the conditioning material can be hardened and removed.
Abstract:
The present disclosure describes optoelectronic modules (e.g., hybrid lens array packages) that have multiple optical channels, each of which includes at least one beam shaping element (e.g., a lens) that is part of a laterally contiguous array. Each optical channel is associated with a respective light sensitive region of an image sensor. Some or all of the channels also can include at least one beam shaping element (e.g., a lens) that is not part of a laterally contiguous array. In some cases, the arrays can include alignment features to facilitate alignment of the arrays with one another.
Abstract:
The method regards manufacturing devices by replication, wherein each of the devices comprises a device surface. The method comprises producing the devices from a replication material by replication using a replication tool (1), wherein the replication tool (1) comprises a tool material comprising replication sites (4) comprising a replication surface (5) each. Each of the replication surfaces (5) corresponds to a negative of the device surface of a respective one of the devices. The tool material comprises, in addition to the replication sites, one or more mitigating features (7) for reducing asymmetric form errors of the device surfaces. Replication tools (1) and methods for manufacturing these are also described.
Abstract:
An optoelectronic module includes a spacer with an optical component mounting surface, a fluid permeable channel, and a module mounting surface. The fluid permeable channel and module mounting surface allow the channels to be sealed to foreign matter during certain manufacturing steps and to remain free from blockages, such as solidified flux, during certain manufacturing steps. Further, the channels can permit heat to escape from the optoelectronic module during operation.
Abstract:
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.
Abstract:
The present disclosure describes modules operable to perform optical sensing. The module can be operable to distinguish between signals indicative of reflections from an object or interest and signals indicative of a spurious reflection such as from a smudge (i.e., a blurred or smeared mark) on the host device's cover glass. Signals assigned to reflections from the object of interest can be used to for various purposes, depending on the application (e.g., determining an object's proximity, a person's heart rate or a person's blood oxygen level).
