Hi Harry,

It's hard to tell from the drawing. If they are truly simple plano-convex
lenses, I can think of two orientations. But with two lenses in two
positions with two choices for orientation, you have 8 possibilities. I
suspect one is larger in diameter than the other, which limits it to 4
possibilities. This may sound silly, but put it together and if it works the
same, great. If not, take it back apart and try again. You'll get it quickly
and feel smarter for having worked it out.

And don't worry about it. You are not the first person to do this. Hang in
there and let us know when you get it!
