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 collimated 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。
The key of the system is that cylindrical lenses by perpendicular double group and equal conjugate are used to image marking shape window to thick and short one.
该系统的核心是用两组互相垂直、且共轭距相等的双曲柱面镜,把激光器的条形窗口的像变粗变短;然后,再用透镜组把此像“准直”到“无限远
