  • Patent number: 10303047
    Abstract: The purpose of the present disclosure is to provide a small optical integrator for increasing color mixing property and homogeneity. An optical integrator is provided with a light entrance surface and exit surface (002, 003), and side surfaces (004, 005, 006, 007) that connect the entrance surface and the exit surface, and is internally filled with a light guide material having a refractive index. The light guide material contains scattering particles for scattering light that have a refractive index different from the refractive index of the light guide material. The light that has entered via the entrance surface propagates from the entrance surface side toward the exit surface while being scattered by the scattering particles in the light guide material, wherein part of the scattered light is guided to the exit surface by propagating while being confined, by internal reflection on the side surfaces, in the light detector.
