摘要 |
The specification describes an energy-beam engraving method for producing depressions of different dimensions in a surface. In the method depressions with smaller and larger dimensions are produced by shorter and longer action of an energy beam with a substantially constant power. Besides the duration of action of the energy-beam on a predetermined range of the surface to be engraved simultaneously its focussing is so varied that the focus plane is closer to the surface in the case of smaller depressions than with larger depressions. |
