LASER MACHINING DEVICE Russian patent published in 1995 - IPC

Abstract SU 1508468 A1

FIELD: laser machining of materials. SUBSTANCE: laser radiation is focussed with set of lenses with decentralized pupils on to mask-template placed in focal plane of set of lenses. Mask-template diaphragms peripheral radiation over external and internal outlines of pattern. Projection lens projects laser radiation on to surface of machined part through holes in mask-template with high resolving power and improved quality of machining. EFFECT: enhanced quality of machining. 1 dwg
