Re: [ATM] On Axis Foucault
The big thing is to get the setup small. The cube beamsplitter will work as
the SA is canceled on the return path. The smaller you can make things, the
better you will be. In addition, the light source needs to be a wide angle
source so that the optic under test is evenly illuminated.
