摘要： PROBLEM TO BE SOLVED: To provide an optical path switching device adaptable even to a high optical intensity of transmission light. SOLUTION: The optical path switching device includes a fixing base 12 which supports a fixed side optical fiber 11a and a movable base 14 which supports and moves a moving side optical fiber 13a, and selectively and optically connects the moving side optical fiber 13 and the fixed side optical fiber 11 by moving the movable base. A collimator lens 20 is fitted to each end of the moving side optical fiber 13 and the fixed side optical fiber 11. The collimator lenses 20 face to each other with a gap between them. The light emitted from the optical fiber is enlarged in its diameter with the collimator lens and shaped into a parallel beam, and directed to the facing collimator lens. The diameter of the luminous flux is large between both collimator lenses, the optical intensity per unit area is thus low even if the intensity of transmission light is high, and thus the possibility of deterioration of the end face state due to dust or the like stuck to the end face of the collimator lenses is minimized. A matching oil is not used, so that a disadvantage due to the matching oil does not occur. COPYRIGHT: (C)2011,JPO&INPIT
