柱面镜

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 model of this collimator set on the ray trace theory. The designing and optimization way are created.

通过该方法设计的准直系统，在实际应用中达到了与传统非球面柱面镜相同的准直效果。

Of course, if the disk is right at the focal length of the objective lens, then the cylindrical lens does not affect the image and it is perfectly circular.

当然，如果正好处于物镜焦距位置，柱面镜就不会影响到光电探测器上的成像，因而会获得一个完美的圆性影像。

The special optical system including a main lens, a spherical -cylindrical lens and an inverting prism was designed.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
