[OpenSPIM] About the cylindrical lens

[Peter Gabriel Pitrone]

Hello Edgar,

Your solution of using the simpler cylindrical lens will work well if you don't use other laser
lines. Stay with the 50 mm focal length, as changing it will change the properties of the
light-sheet. I'm in the process of testing different lens combinations, and will update the wiki
accordingly as to what I find.

Best Regards,
Pete
