Heteroaxial double half-cylindrical lens collimate beam of laser diode ［J］.

异轴双半圆柱透镜准直半导体激光光束［J］。

Double half-cylindrical lens collimate the beam of laser diode .

双半圆柱透镜准直半导体激光光束。

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
