る ことを特徴とする光学装置。[Claims for Utility Model Registration] A prism is fixed with an adhesive on a semiconductor substrate on which a photodiode is formed on the surface, and a beam of light that travels inside the prism toward the photodiode obliquely with respect to the surface thereof. An optical device in which a portion of the light is internally reflected on a surface of the prism on the semiconductor substrate side, and the remaining portion is transmitted through the surface and received by a photodiode, the optical device comprising at least a photo of the surface of the prism on the semiconductor substrate side. An optical device characterized in that a portion corresponding to the diode is brought into contact with the surface of the semiconductor substrate either directly or via a substance having a higher refractive index than the adhesive.
