PURPOSE:To form a laser light transmission equipment with high degree of freedom of operation by forming the equipment by an intermediate bending member, an incident side bending member and an outgoing side bending member. CONSTITUTION:The incident side bending member 11 and the outgoing side bending member 13 based on the intermediate bending member 12 can be optionally rotated around an incident optical path 14 and an outgoing optical path respectively in rho and psi directions. Thereby, the relative positions of the members 11, 13 can be optionally changed in the three-dimensional direction. A laser light L made incident on the bending member 11 through an incident tube 1 is projected in the direction of an outgoing tube 6 through the members 12, 13 after being bent by an incident side laser mirror 20, an intermediate laser mirror 16 and an outgoing side laser mirror 23 in order without fail even if the members 11, 13 are arranged on any relative position relation. Thus, the laser light L can be transmitted in an optional direction. |
