日本PEAK放大鏡說明
放大鏡是用來觀察物體細(xì)節(jié)的簡單目視光學(xué)器件，是 焦距 比眼的明視距離小得多的會聚透鏡。物體在人眼視網(wǎng)膜上所成像的大小正比于物對眼所張的角（視角）。視角愈大，像也愈大，愈能分辨物的細(xì)節(jié)。移近物體可增大視角，但受到眼睛調(diào)焦能力的限制。使用放大鏡，令其緊靠眼睛，并把物放在它的焦點(diǎn)以內(nèi)，成一正立虛像。放大鏡的作用是放大視角。為作比較，物放在明視距離 s 0 （250毫米）處，裸眼觀察時的視角為 j ，用放大鏡觀察時，令虛像也位于明視距離處，視角變?yōu)?j ′。定義視角放大率（或稱放大倍數(shù)）為

在傍軸條件下，視角放大率為
式中 f 為放大鏡的焦距，有 s 0 >> f 。焦距愈短，放大倍數(shù)愈高，但由于受到像差的限制，單個凸透鏡的放大倍數(shù)一般不超過3，組合消 像差 透鏡的放大倍數(shù)可提高到20左右+556
