LASER BEAM DEVICE

摘要

PURPOSE:To execute a multipoint simultaneous working and to shorten the working time by arranging a laser oscillator and lens on plane and providing the converging optical device installed in the optical path of the laser beam emitted from the oscillator. CONSTITUTION:The laser beam 2a emitted out of a laser oscillator 1 is made incident on the converging optical device 8 which arranges the lenses 3, 4 whose one part of the faces at least is a plane in one or plural rows on the plane and which is installed at the optical path inside of the laser beam emitted from the laser oscillator 1. A multipoint simultaneous working is available in the state of taking the distance between the converging optical device 8 and work 10 by arranging the focal point thereof to locate at the vicinity of the surface of the work 10, the working time is shortened and the working can be done with good pitch and accuracy.
