凸透镜的屈光、成像和应用凸透镜的屈光、成像和应用凸透镜亦称为正球透镜，镜片中央厚，周边薄，呈凸形，所以叫做凸透镜。平行光线通过凸球面透镜发生屈折后，与主轴相交于一点（PF），成为集合光线，因此，凸透镜又称为集合透镜。所相交的点（PF）为主焦点，是平行光的实性焦点，图19.凸透镜的成像可用几何作图法来表示。从物体的顶端（A）作两条直线，一条与主轴平行，经过透镜后发生屈折，改变方向（Da），通过主焦点F2；另一条通过镜片的光学中心点（O），这两条线相交于a点，此即为物体A点的像，图20.凸透镜的成像取决于物体与镜片的距离。物体（AB）位于主焦点（F1）以远，在镜片的另一侧可形成一个比物体小的、倒置的实像（ab），如图20所示。如果物体（AB）移至主焦点（F1）以内，则在镜片与物体同侧形成一比物体大的、直立的虚像（ab），如图21所示。凸透镜可应用于矫正远视眼、老视眼和无晶状体眼。照相机和幻灯机的镜头亦为凸透镜。
