发明名称 Light sensor having transparent substrate with lens formed therein
摘要 Light sensor devices are described that have a glass substrate, which includes a lens to focus light over a wide variety of angles, bonded to the light sensor device. In one or more implementations, the light sensor devices include a substrate having a photodetector formed therein. The photodetector is capable of detecting light and providing a signal in response thereto. The sensors also include one or more color filters disposed over the photodetector. The color filters are configured to pass light in a limited spectrum of wavelengths to the photodetector. A glass substrate is disposed over the substrate and includes a lens that is configured to collimate light incident on the lens and to pass the collimated light to the color filter.

主权项 1. A light sensor comprising: a substrate having a surface; a photodetector formed in the substrate proximate to the surface, the photodetector configured to detect light generated from a single illumination source and to provide a signal in response thereto; at least one color filter disposed over the photodetector, the at least one color filter configured to pass light in a limited spectrum of wavelengths to the photodetector; a transparent substrate disposed over the substrate, the transparent substrate including a lens configured to collimate light incident on the lens and to pass the collimated light to the at least one color filter; and an IR suppression filter disposed between the at least one color filter and the transparent substrate, the IR suppression filter configured to filter infrared light to at least substantially block infrared light from reaching the at least one color filter.
