Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] 直角プリズムの直角をはさむ２辺をそれぞれ入射面と出
射面とし、斜面に一部透過型の反射膜部を介して平行平
面板を光学的に結合し、入射面から入射した光を反射膜
部によって分割し分割された光を出射面から射出させ、
他方の光を平行平面板の面によって出射面方向に反射さ
せる光分割器。The two sides that sandwich the right angle of the right angle prism are used as the incident surface and the output surface, respectively, and a parallel plane plate is optically coupled to the slope via a partially transmissive reflective film section, and the light incident from the incident surface is reflected by the reflective film section. The divided light is emitted from the output surface,
A light splitter that reflects the other light toward the output surface by the plane of a parallel plane plate.
