各位大侠，请教：如何将Φ6光束变为12×2的椭圆或者方形光斑。我已经产生了12×6的椭圆形光斑，下面如何缩束生成12×2的光斑。

用块柱透镜试试看

用棱镜整形可以做到这个。

if you dont not care flux lost or if you can couple the light well, i think you might try an asymmetrical lens, with different power in horizontal and vertical directions that magnifies the input beam differently.

if the light beam is incoherent, you can use a light guide which are just mirrors enclosing the propogation path. you can use lightools to simulate the output pattern buy using four mirrors to form a rectangular shape.
