宝石鉴别拉曼光谱仪是采用光致发光(PL)
光谱仪技术制造的双重用途的高级宝石测试系统,适合经验丰富的珠宝估价师、宝石买卖商、矿物收藏家、地球科学应用研究人员和实验室人员使用。
宝石鉴别拉曼光谱仪可以快速分辨钻石、立方氧化锆、玻璃和锆石之间的区别,区分天然翡翠和聚合物处理的翡翠,以及软玉,区分真假珍珠,分辨它是象牙还是塑料;它适用于珠子、雕刻、镶嵌在珠宝和粗矿物中的宝石材料(无需准备)。它在检测宝石的辐照、HPHT和其他颜色增强等处理方面非常有效;它将有助于确定钻石和宝石的性质,并可识别3500多种矿物(粗糙和抛光样品)。
宝石鉴别拉曼光谱仪光谱可以保存,可选集成光谱库匹配(在不到1秒的时间内),或导入一个单独的可搜索数据库程序,其中包含3500多个编辑参考文献;该数据库与拉曼光谱大型在线矿物学RRUFF数据库相连。
