Though the index of refraction of synthetic calcium fluoride has been determined, little data exist on neodymium doped calcium fluoride. Measurements of the index of refraction of synthetic calcium fluoride doped with 0.001, 0.01, 0.1, 5, 1, and 10 mol % neodymium at 16 wavelengths from 4358.35 A to and including 6678.15 A at 25 degrees C have been made. Most values are believed accurate to +/-3 x 10(-5). The index of refraction at three wavelengths has been measured at 15 degrees C, 25 degrees C, 35 degrees C, and 55 degrees C, and at one wavelength at about these same temperatures. Data are also included on a series of five neodymium doped glasses.
虽然已测定了合成氟化钙的折射率，但关于掺钕氟化钙的数据却很少。已对在25摄氏度下，掺杂了0.001%、0.01%、0.1%、5%、1%和10%摩尔分数钕的合成氟化钙在4358.35埃至6678.15埃（包括该范围）的16个波长处的折射率进行了测量。大多数值被认为精确到±3×10⁻⁵。已在15摄氏度、25摄氏度、35摄氏度和55摄氏度下，对三个波长处的折射率进行了测量，并且在大约相同温度下对一个波长处的折射率进行了测量。数据还包括一系列五种掺钕玻璃的相关数据。
