DEVICE FOR USE IN LIGHT-BEAM PROCESSING

摘要

A device for use in the light-beam processing of materials comprises a point optical light source (1) and a concentrating reflector (2) with a reflecting surface in the form of a surface of rotation. The generatrix of the surface of rotation of the concentrating reflector (2) is formed by the arcs of co-focal ellipses (3), segments of beams (4) originating from the focus which coincides with the light source (1) and ellipses connecting the ends of the said arcs and the arc of circumferences (5) with their centre at that focus. The dimensions of the boundary segments and their configuration are determined taking into account the requirement to gather the maximum amount of light from the point source (1) in the region of the focal point on the surface of the material undergoing treatment while retaining the greatest possible freedom to change the reflector's shape.
