摘要
根据色度学原理,以绿色色调的翡翠为研究对象,利用USB2000＋光纤光谱仪,对样品的光谱反射率曲线和光谱色度学参数进行分析.结果表明：淡绿色翡翠样品的光谱反射率曲线较平缓且光谱反射率大多位于10%~20%之间;绿色较淡至浓的翡翠样品的反射率曲线反射峰尖锐且反射率多位于10%~30%之间.对绿色翡翠来说,色调角在（195°,225°）,主波长为488~492 nm时,其色调为蓝绿色;色调角在（180°,195°）,主波长为492~497 nm,其色调为泛蓝的绿色;色调角在（165°,180°）,主波长为498~509 nm,其色调为绿色;色调角在（150°,165°）,波长为528~538 nm,其色调为泛黄的绿色.
In this paper,the reflection curves and colorimetric parameters of jadeite are studied using the USB2000 ＋ fiber spectrometer. According to the principle of colorimetry,the analysis shows that reflection peak of light green jadeite is not sharp and the reflectivity is 10% ~ 20%. But for green jadeite,the reflection peak is sharp and the reflectivity is 10% ~ 30%. For these samples,when the hue angle is in 195° ~ 225° and the dominant wavelength is 488 ~ 492 nm,its hue is bluish green; when the hue angle is in 180° ~ 195° and the dominant wavelength is 492 ~ 497 nm,its hue is blue green; when the hue angle is in 165° ~ 180° and the dominant wavelength is 498 ~ 509 nm,its hue is green; when the hue angle is in 150° ~ 165° and the dominant wavelength is 528 ~ 538 nm,its hue is yellow green.
