This is a GREAT shop tool. Made by Perkin-Elmer and is SN 002. Not sure if they made any more than two as I have never seen another. Easy to set up and it can test both coated and uncoated optics. Comes with instructions on how to set it up. The same instructions I got with it when I bought it 20 years ago. Supplied with a robust xyz stage. Interferometry doesn't get any easier than this.

$7,500 + shipping lower 48 States.
