  • Photodetection device having a light passing part, a light guide member, and a photodetection element
    Patent number: 9358919
    Abstract: A photodetection device has a light passing part in an upper portion, a light guiding member, and a photodetection element in a lower portion. Light passing through the light passing part is guided by the light guiding member to be detected by the photodetection element. The light guiding member has an incident curved surface provided annularly around a central axis on a side of the light passing part, and a reflective curved surface provided around the central axis inside the incident curved surface so as to be opposed to the incident curved surface. The light guiding member reflects light at the reflective curved surface to guide the light to a light receiving surface of the photodetection element, the light passing through the light passing part and entering the incident curved surface at a predetermined inclination angle.
