All I wanna do is re-collimate a diffuse laser reflection...
35 mW of very green laser light shining on a small white plastic object is BRIGHT. The light seems readily-enough gathered with a large objective lens, but I get hung up there time and again.
Should I be using smaller gathering lenses and/or pinhole optics in some way?
Or hell, am I better off trying to gather the light with some sort of convex mirror?

Note: my desired gathered/focused/collimated output does not need to be a tiny beam - in fact, a beam with some surface area is preferable.

Can this be done with standard optics?
