Method for evaporating, destroying, exciting and/or ionizing specimen material limited to micro-regions, and arrangement for carrying out this method

摘要: Method and apparatus for examining micro-regions of biologic specimens normally radiation absorptive in which a source coherent electromagnetic is optically focused on selected region the specimen. The power density adjusted central diffraction disk to point where specimen becomes absorbent, distribution first ring being below level necessary initiate absorption said ring. In its preferred form, fed microscope having cooled objective through focusing micro-region achieved.
