I focused these lenses so that we could get a clean image of the mirrors and the OSEMs.

Our goal is to have an image where the optic diameter almost fills the entire monitor. We want the focus to be adjusted for the YAG beam (which is almost the same as focusing for the OSEMs). This will NOT produce a nice image of the cage using visible light, but that is just fine.

When Justin Garofoli was here he found a nice lens combo that did the job, so if anyone can find his old email or elog, lets just go back to that.

For now, we do not need a camera/lens system to focus very tightly on the center of the optic.
