Kenom;

I just might do that, after I finish some testing I am working on.

I don't have a Meridith for Red to test against.

I asked Milos to test this new one, but he is over in Europe playing around.

Since your beast takes a C-mount, it will need a good AR lens for those hi-power Reds & IR's.

I have used 405nm suitable lenses for 650nm laser. It works fine, but a 650nm suitable lens does not work as good with a 405nm laser....

There is also one more thing about short-focal lenses, is that the longer wavelegth the greater will the beam divergence be.

What are the beam specs like using these lenses? And do you have some comparison pics?
