微型光纤光谱仪用于宝玉石定性鉴定测量研究

Qualitative research on micro fiber spectrometer applications in gem identification

光谱分析广泛地应用于宝石鉴定领域,但目前所使用的光谱鉴定仪器不利于光谱鉴定的微型化,因此利用微型光纤光谱仪作为分光检测装置进行宝石的光谱测量,可作为一种便携的光谱检测手段,将成为未来的发展方向。采用荷兰爱万提斯公司产微型光纤光谱仪和复合光源配合使用的方式,对合成红宝石、蓝宝石、黄晶、紫晶、翡翠、云母样品进行谱线分析,并总结其特征谱线用于宝石的定性鉴别。实验表明,微型光纤光谱仪可运用于宝石紫外—可见吸收光谱测量,能实现在线光谱检测,具有一定的应用前景。

Spectrum analysis is applied widely to gemstone identification field. But in the current spectrum identification equipment weighted against miniaturization. With the development of technology, holland avantes micro fiber spectrometer is the future development target as measure of spectrum. This paper tests the characteristic line of ruby, sapphire,citrine,amethyst,jadeite and mica,and analyse their features. Summarizing the characteristic line can be used in the qualitative appraisal of gem. Micro fiber spectrometer can apply in the UV/VIS absorption spectrum measure of gem,it can realize the spectrum measure online and it have certain development trend and application prospect.
