本文根据莫尔偏转法原理提出了一种测量单透镜折射率的改进方法,使单透镜折射率的实测精度为△n=2×10~(-4)。文中还讨论了温度对单透镜折射率测量的影响,提出了排除温度影响的简单措施。
In this paper, an improved method for measuring the refractive index of a single lens is proposed based on the principle of the Moiré deflection method. The measured refractive index of a single lens is Δn = 2 × 10 ~ (-4). The paper also discusses the influence of temperature on the refractive index measurement of single lens and proposes a simple measure to eliminate the effect of temperature.
