本文采用环形横向剪切干涉法和折射计相结合来测定透镜或胶合透镜的拆射率和色散.讨论了该方法的测量精度及提高灵敏度等有关问题.

This article summarizes the measuring methodes of lens refraction index and the drawback of them. We measure both the refraction index and dispersion of lens by encircling lateral shearing interferometer incorporated with a refraotometer. Tho attainable measurement accuracy, the measuring method of cemented doublet and the method of improving the sensitivity are discussed.
