Elemental analysis of materials by laser emission spectrometry, involves directing laser beam by optical beam-shaping element towards material sample and in material sample, and inducing plasma by laser beam

摘要

The process involves a laser beam (2, 4, 7) which induces a plasma (8) in a material sample (9) whereby optical emissions (14) emanating from the plasma are evaluated spectrally. The laser beam is directed by an optical beam-shaping element (6) towards the material sample and in the material sample, distribution of power density over beam width of laser beam produces multiple intensity points. An independent claim is also included for a device for the elemental analysis of materials.
