日本PEAK放大镜说明
放大镜是用来观察物体细节的简单目视光学器件，是 焦距 比眼的明视距离小得多的会聚透镜。物体在人眼视网膜上所成像的大小正比于物对眼所张的角（视角）。视角愈大，像也愈大，愈能分辨物的细节。移近物体可增大视角，但受到眼睛调焦能力的限制。使用放大镜，令其紧靠眼睛，并把物放在它的焦点以内，成一正立虚像。放大镜的作用是放大视角。为作比较，物放在明视距离 s 0 （250毫米）处，裸眼观察时的视角为 j ，用放大镜观察时，令虚像也位于明视距离处，视角变为 j ′。定义视角放大率（或称放大倍数）为

在傍轴条件下，视角放大率为
式中 f 为放大镜的焦距，有 s 0 >> f 。焦距愈短，放大倍数愈高，但由于受到像差的限制，单个凸透镜的放大倍数一般不超过3，组合消 像差 透镜的放大倍数可提高到20左右+556
