摘要
本文介绍了镜片测度仪的原理及有关计算问题,以牛顿公式为基础建立了仪器的工作方程。当a=0,十字分划板移动量和被测镜片屈光度值成线性关系。文中还讨论了几项应注意考虑的误差问题。
The optical principle and calculation of lensmeter are introduced. Based on Isaac Newton's formula, the working equation is proposed for the instrument. If a = o, then the relations between the movement of optical crosshairs and the diopter of lens presents a linear correlation. Some problems about the main errors of the lensmeter which should be cosidered, are discussed in this paper.
