摘要: An optical probe receives an optical signal output from a test subject. The optical probe includes an optical waveguide composed of a core portion and a cladding portion disposed on an outer periphery of the core portion, wherein an incident surface of the optical waveguide, which receives the optical signal, is a convex spherical surface with a constant curvature radius.
