PURPOSE:To perform instantaneous spectrochemical analysis at a place where a material to be analyzed is present, by providing an optical fiber, which transmits laser light, and an optical fiber, which transmits the light that is emitted from a sample owing to the irradiation of the laser light. CONSTITUTION:A laser device 1 is provided with a second high frequency generating element and a Q switch pulse generating element. The generated laser light irradiates the sample 6 through a condenser lens 2, the first optical fiber 3, a condenser lens 5, and an output intensity control device 4. The light emitted from the sample 6 is inputted into a spectrophotometer 8 through the second optical fiber 7, and the light emitting spectrum is measured. In this way, the spectrochemical analysis can be instantly performed at the place where the material to be analyzed is present, without moving the spectroscope at civil engineering working sites, at the sea bottom in a very deep region, and the like. |
