PROBLEM TO BE SOLVED: To provide a mechanical optical switch in which alignment adjustment of appropriately matching the relation of respective optical axes is facilitated, optical axis misalignment is prevented and which has high stability and reliability of a switch operation and is advantageous for the demand of miniaturization. SOLUTION: Two collimators 6 are oppositely attached to a housing 11 roughly in a block shape to form an optical unit 1 of continued optical axes, and the collimators 6 are provided with an input port p1 and output ports p2 and p3 by an optical fiber 5. An optical element 2 (mirror) is attached to a linearly displacing movable member of a displacing unit 3 and a driving means 4 for driving the movable member is fixed to the housing 11. For that, the state of positioning the optical element 2 inside an attaching hole part 13 almost at the center of the housing 11 is attained and the relation of the respective optical axes is appropriately matched. In such a manner, since both assembled into unit bodies are fixed, work is easily performed. COPYRIGHT: (C)2004,JPO |
