激光显微光谱分析是近十几年来发展起来的新型微区分析技术。它是利用激光能量高度集中、单色性、方向性好的特点,把激光光束聚焦到样品上,使其蒸发激发,用摄谱或光电记录等方法,可对试样中几十微米至几百微米的微区,进行Li—U等近70个元素的分析。操作简便、分析速度快,既不需预先处理试样,也不破坏样品原形。因此,激光显微光谱分析在地质、冶金、医学、考古、科学研究等部门获得了广泛的应用。在地质研究方面,激光显微光谱分析有着重要的用途。它既可以测定挑出来的一颗矿物
Laser microspectroscopy is a new type of micro-area analysis developed in recent ten years. It is the use of laser energy is highly concentrated, monochromatic, good directional characteristics, the laser beam focused on the sample, so that the evaporation excitation, with photo or photoelectric recording and other methods, the sample can be tens of microns to a few One hundred microns of micro-area, Li-U and other nearly 70 elements of the analysis. Easy to operate, fast analysis, neither pre-treatment of the sample, nor destroy the original sample. Therefore, laser microspectroscopy has been widely used in geology, metallurgy, medicine, archeology and scientific research. In the field of geological research, laser microscopy has important uses. It can measure a pick out of a mineral
