| Abstract: | 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. |
| Keywords: | lateral shearing interferemetrio pattern disporsion. |
