圆柱镜

By using two groups of cylindrical lenses perpendicular to each other, the marking shape window of semiconductor laser is imaged and rectangle and this imagery is then collimate d to infinite by collimating objective.

利用互相垂直的两组圆柱面镜把半导体激光器的条形窗口成像为矩形。再用球面准直物镜组把此象"准直"到"无限远"。该系统把激光器发出的发散光束压缩到在±0.0025弧度内出射光。两组柱面镜的同种倍率互为倒

The cross cylinderis a compound lens having a net minus power in one principal meridian and an equal net plus power in the other.

12交叉圆柱透镜(Jackson 交叉柱镜)是一组复合式镜片，一条主子午线上有单纯负圆柱透镜焦度，在另一主子午线上有一相等的单纯正圆柱透镜焦度
