用V棱镜法对高折射光学材料进行折射率(1.80＜nd＜2.00)测试过程中，样品和V棱镜间需滴加折射率与样品相等的折射液，以起到消除样品90°角度加工偏差的作用。而现阶段生产使用的折射液nd最高仅能达到1.78，造成了样品折射率测试值与真实值之间的较大偏离，最大偏离量可达20×10-5。本文通过对 V 棱镜测试法的光路研究，找到高折射率样品测试值与真实值之间的偏离机理，通过计算折射率偏离量来补偿样品测试值的方式，使补偿后的折射率偏离量在±4×10-5以内，实现了V棱镜法高折射光学材料折射率测试的精度要求(±5×10-5)。

This article refers to the test for refractive index of high-index material (1.80<nd<2.00)by using a V-prism test method, and the index liquid whichnd is equal to the sample need to be dropped into the linking face between V-prism and sample, in order to eliminate the sample angle of 90° processing deviation . Since the highest refractive index is only at 1.78 of existing index liquid, greatnd deviation between the tested data and true value comes out in this test, and the greatest refractive index deviation has reached to 20×10-5. Now we have found out the discrepancy principle of high-index sample test data by the light refractive route research of V-prism test method. By means of calculating refractive index deviation to compensate test data, make the deviation of compensated refractive index reduce to ±4×10-5. Therefore, the measuring accuracy (±5×10-5) of high-index glass is ensured by our V-prism method.
