Hyperbolic Lens. Scale to change size or focal length. Can be cut in half to form a plano-convex lens.

How does that work?
Actually, now that I looked at it mathematically and Algodooically, I can see that it does not retain its focus accurately when scaled. So the answer is that it doesn't work.

The parabolic reflector does scale and retain its focus.
Looks like somebody really hated this scene (rated it a 1), but was afraid to say why.
