  • Solid-state image sensor with microlens and optical fiber bundle
    Patent number: 5844289
    Abstract: An improved solid-state image sensor is provided by having an image sensing element composed of photoelectric conversion parts, a microlens formed on the surface of the image sensing element corresponding to each photoelectric conversion part, and optical fiber bundle formed of optical fibers arranged in a two-dimensional shape and mounted on the microlens. The optical fiber bundle is also composed of a core and a clad portion. The refractive index of a filler which mounts the optical fiber bundle on the microlens is less than that of the microlens and greater than that of the clad portion of each of the optical fibers.
