测定薄凸凹透镜折射率和曲率半径的简单方法

Simple Method of Measuring the Refractive Index and Radius of Curvature of Thin Convex-concave Lens

介绍了薄透镜焦距测定中观察到的薄凸凹透镜对物的球面反射成像及折—反—折成像，指出利用这一现象可较好地测定薄凸凹透镜的折射率及前后表面的曲率半径。并对实际透镜进行了测定，结果准确。

In this paper images caused by spherical refraction and reflection-refraction- reflection observed in measuring thin-lens′s focal distance are intruduced.The images can be used to measure the refractive index of thin convex-concave lens and the radius of curvature of its fore and rear surfaces.The lenses are also measured practically and the experimental results are accurate,which prove it to be a better method.
