There are lot, depending on your requirements. Anyway you can try: S{;Pga*Px s;9Du|0f^ 1, Refractive: an achromatic as positive + plano-convex as negative; a{T.U-0
OR >n09K8
A 2, Reflective: two parabolic mirrors; Y 3ApW vS -_ I)5*N Both of them affer nice spherical aberration performance. />S^`KSTM _eiqs Reminder: compute the laser beam density, ensure you have enough strong optical coating. XG.[C> w li cuY? Good luck.
Hi, TWp w/osW +^Xf:r`
G The following is a link of technical data of optical adhesives, hope it be helpful: ^w^e~0

如果你用的是1064的激光,那么采用双胶合并不是一个明智的方案,除非真正能解决胶的问题,你的能量有大?采用双胶合,你考虑过没有它的可靠性? S.!,qv z 如果ZEMAX对系统的公差分析,精度要求控制在1u,那么你就应该放弃这样的方案。 4^W!,@W 这类系统我也做过,没有遇到你这种情况,“要求正向使用(扩束)和反向使用(缩束)时产生的像差相同”-
