There are lot, depending on your requirements. Anyway you can try: a$}mWPp+f ("Dv>&w9 1, Refractive: an achromatic as positive + plano-convex as negative; 7X'y>\^w^> OR _Bk
U+=|J 2, Reflective: two parabolic mirrors; b3U6;]|x RP`
`mI Both of them affer nice spherical aberration performance. +LzovC@^ (@&I_>2Q Reminder: compute the laser beam density, ensure you have enough strong optical coating. x /
XkD]Hq =B(mIx;m Good luck.
