発明の名称 (英語) COMPONENT COMPOSITION MEASURING SYSTEM AND COMPONENT COMPOSITION MEASURING METHOD NEW
発明の概要(英語) This component composition measuring system is provided with: a first laser light source which radiates first laser light (L1), having an intensity sufficient to generate plasma, onto an object to be measured; a second laser light source which radiates second laser light (L2), having an intensity not sufficient to generate plasma, onto the object to be measured; a spectrum measuring device which measures a light-emission spectrum indicating the intensity at each wavelength, from plasma emissions generated by radiating the first laser light onto the object to be measured; and a control device which uses data relating to the measured light-emission spectrum to analyze the composition of the object to be measured. The second laser light source starts radiating the second laser light (L2) before the start of radiation of the first laser light (L1), and stops radiating the second laser light (L2) after radiation of the first laser light (L1) has stopped.
