拉曼光谱效应由印度物理学家C.V.Raman于本世纪初发现,迄今已在科学领域得到广泛应用,近年来也应用于宝石学领域。通常拉曼光谱显微镜由这样几部分组成:宝石显微镜,低能激光源,光谱仪和计算机。拉曼光谱显微镜具分辨率高、无需制样、无损鉴定等特点,所以适用于宝石学领域。通常是将样品所测光谱与标准光谱进行比较后可得出正确结论,以下列举一些实例。
The Raman spectrum effect was discovered by Indian physicist C.V. Raman at the beginning of this century and has been widely used so far in the field of science and has been applied to the field of gemology in recent years. Raman microscope usually consists of several parts: gem microscope, low-energy laser light source, spectrometer and computer. Raman spectroscopy microscope with high resolution, no sample preparation, nondestructive identification and other characteristics, so apply to the field of gemology. It is usually the result of a comparison between the measured spectrum of a sample and that of a standard spectrum. Some examples are given below.
