摘要： An optical apparatus is disclosed, which can take high-quality images by using light transmitted through a beam splitter. The optical apparatus comprises a light-receiving element and a beam splitter. The first surface of the beam splitter reflects part of incident light and transmits the other part of the incident light toward the light-receiving element. The second surface transmits other incident light other than the incident light to the first surface toward the light-receiving element. The transmittance of the second surface is set so that a light amount distribution on the light-receiving element may be substantially even in a case where the light is incident to the first and second surfaces from an object having a substantially even luminance.
