Anyone made a tester using a microsope xy stage?  The stage itself is 5" square and each one has 2 inches of total travel.  The microscope holder also a degree of travel.  Looking for solutions for the LED and knife edge if anyone has em.

 

I'm reluctant to drill into the microsope holder to mount the LED.  It's a very nicely bit of machined aluminum.  I was thinking of cutting a round plug that would fit in the microscope holder hole and running the LED and KE off that.

 

Any ideas are welcome!

That would also work very well for a bath interferometer stage.

Not as rugged, but more compact.GEDC1623 (Mobile).JPG GEDC1624 (Mobile).JPG

Miniaturization is nice, but light and small testers should be either fastened to the bench or they should be heavy enough not to move or vibrate when touched. 

 

My Bath IF, although it's rather heavy for its size, attaches to a 3/4" thick aluminum plate, or is bolted to the bench, when in use.

Agreed, that's what the holes in the base are for.
