<P>PROBLEM TO BE SOLVED: To provide an optical fiber end part observation device which can vary a magnification continuously and steplessly from a high magnification to a low magnification by one imaging unit and can be accurately focused. <P>SOLUTION: An optical fiber 1, an objective lens 3, and a camera 4 are provided on the same optical axis, and moving means is provided which can move the objective lens 3 and the camera 4 toward or away from each other independently relative to the positioned optical fiber 1. The moving means comprises: a camera fixing base 7 which is freely movable on a base 6 and has the camera 4 fixed thereto; a camera driving device 8 which moves the camera fixing base 7; an objective lens fixing base 9 which is freely movable on the camera fixing base 7 and has the objective lens 3 fixed thereto; and an objective lens driving device 10 which moves the objective lens fixing base 9. <P>COPYRIGHT: (C)2013,JPO&INPIT |
