NEVERMIND.....Aspheric double convex condenser lens.

[MoreGooder]

Has anyone tried using a "condenser" lens as shown below in a flashlight instead of a more traditional aspherical lens?

I know that they are used in microscopes, as described in a condenser lens wiki:

But, what would this do in a flashlight? Note that the suplushshed website describes it as a "double convex" lens, meaning that both surfaces are curved outward, one significantly more than the other.

I found what I needed to know. I just had to do a different search in our forums.

Move on.... nothing to see here....

I am curious about this topic too, where did you find the answer? Can you post the relevant thread?
