| 摘要 |
The invention relates to a portable laser spectrometer destined to the emission spectral analysis with application in the elemental qualitative and quantitative analysis of metals and metal alloys and also in the analysis of ores, ceramics, glass and the like. According to the invention, the spectrometer comprises a probe (1), a miniature spectrometer (2) provided with a fixed diffraction grating and a Diode-Array detector, a fiber optic packet containing a central optical fibre (3) and several optical fibres (4) radially symmetrically arranged around the central optical fibre (3) inside a protection polymeric material (5), a medium power laser unit (6) for locally fusing the surface of a material (7) to be analyzed, a focusing lens (8), a laser telemeter (9) for maintaining constant the distance and for targeting the examined area, a button (11) for controlling the laser excitation and a portable computer (12) for data processing. |
