Document Type and Number:
Japanese Patent JP3142386
Kind Code:
B2
Abstract:
PURPOSE: To quickly and accurately align optical axes when a laser beam is transmitted in a long distance.
CONSTITUTION: As a movable mirror device, a mirror holder 12e which is rotatably provided at the upper part of a supporter 12c made to stand on the supporting table 12b of a laser axis and which axially supports a mirror 12d with a recessed upper inside part as a holding part, an interlocking arm 12g which is provided so as to be interlocked with the mirror 12d on the upper outside of the holding part and whose lower end is faced to the holder 12e, a fixed arm 12h fixed to the supporter 12c, a rough adjustment mechanism 37 which turns the holder 12e by making a rod 37a moving forward and backward by an adjustment signal abut on the arms 12g and 12h and plural fine adjustment mechanisms 38 which are made to intervene between the mechanism 37 and the surface of the mirror holder opposite to both arms 12g, 12h and cylindrically formed so as to be finely made to contract or elongate by receiving the adjustment signal are provided.
