Optical sensor

摘要

The present disclosure relates to an optical sensor module, an optical sensing accessory, and an optical sensing device. An optical sensor module comprises a light source, a photodetector, and a substrate. The light source is configured to convert electric power into radiant energy and emit light to an object surface. The photodetector is configured to receive the light from an object surface and convert radiant energy into electrical current or voltage. An optical sensing accessory and an optical sensing device comprise the optical sensor module and other electronic modules to have further applications.

主权项

1. An optical sensor module comprising:
a substrate; a light source disposed on the substrate; a first encapsulant formed over the light source; a photodetector disposed on the substrate; a second encapsulant formed over the photodetector; a partition coupled to the substrate and located between the light source and the photodetector; and a microstructure formed on an outer profile of at least one of the first encapsulant and the second encapsulant; wherein each of the first encapsulant and the second encapsulant has a top surface and a medial surface, the medial surface is between the substrate and the top surface and is substantially facing the partition, and the partition is spaced apart from the medial surface of the at least one of the first encapsulant and the second encapsulant by a predetermined distance.
