摘要
利用焦度计测出眼镜片的光焦度,再由杠杆千分表、量块和测量环等测出相关量,计算出眼镜片表面的曲率半径,求得眼镜片的折射率.
The focus power of eyeglass was measured using lensometer ,and some other parame-ters could be measured using dial test micrometer ,gauge block ,check ring and so on .T he radius of curvature of eyeglass surface and the refractive index of spectacle lens could be calculated based on these results .
