Optical device for laser machining |
摘要 |
A unit for splitting a laser beam into a plurality of beams is provided separately from a converging unit so that both units can be manufactured easily, replaced at low cost and are less likely to be polluted or damaged during laser machining. A laser beam produced by a laser oscillator and guided into a machining head through a transmitter is split into a plurality of beams by a plane reflecting mirror. The laser beams thus split are reflected by another reflecting mirror having a single paraboloidal surface so as to be converged on focal points. The first plane reflecting mirror comprises two semicircular mirrors which can be inclined independently of each other. <IMAGE> |
