我要设计一个激光扩束镜,要求正向使用(扩束)和反向使用(缩束)时产生的像差相同。请问采用什么样的结构才可以实现? bbe$6x wi 最好是伽利略结构的(无实焦点),实在不行的话也可以用开普勒结构。

用伽得俐略的系统是比较长用的,这样做的系统毕较短

There are lot, depending on your requirements. Anyway you can try: c0aXOG^ (<KFA, 1, Refractive: an achromatic as positive + plano-convex as negative; E>I\m!ue OR 4}xw&x 2, Reflective: two parabolic mirrors;
bo|3sN+D iKM!>Fi Both of them affer nice spherical aberration performance. :}* $s]vZ(H Reminder: compute the laser beam density, ensure you have enough strong optical coating. )sZJH9[K c$P68$FB Good luck.
Hi, Q].p/-[( l=PZlH
y1G The following is a link of technical data of optical adhesives, hope it be helpful: /Os6i&; SceK$ http://www.lienhe.com.cn/uvadh/NOA60.htm dt|| nF aY-7K._</ Double check from your lens vendor waht type of adhesive they use for your cemented doublet.
