They also have rack and pinion microscope stages, heavy duty, new, which make excellent translation stages for variable linear beam splitters. I am going to try one for spatial filter mounting.
Thanks again to Colin as this source came from his page.

I bought one of the microscope stages a few months back and it works great for my variable beam splitter. I actually disassembled it in two parts and gave one to Michael which I believe is also using it successfully for his beam splitter.

I got to use Michael's beamsplitter and the adjustment was great! This is a really good idea. Thank you.

I looked at one of the 4x's and one of the 10x's. The 4x was very very clean. The 10X was terrible. I did not try to clean either of then. I used them right out of the case. It may be all surface on the 10x. Unfortunately I was pressed for time in my session and only needed to use the 4x.
