Does anyone know of a source of small, very light weight plastic lenses?
Particularly plano-concave lenses? Thanks.

How small is a small lens? Smaller than the ones Thorlab sells?

Surely somebody here has to know of an optics company that sells small
lenses!

You would think. But when you try lenses, you get how and what they are
for and very few  to no suppliers. It's interesting that the folks at
alt.sci.acoustics are a much more helpful lot; funny, I never thought
I'd ever hear myself say that...

Ron,
  Go to www.photonicsdirectory.com and click on the buyers guide and then
click on P and then scroll down to plastic optics.  This will give you a
listing of suppliers.
