Inge, What you might be describing is an optical comparator. I looked and there is no picture of such thing in dropbox. Ed Popielarski Engineering Manager 970 NE 21st Ct.

The great madness was going on at the company where I used to work. Restructuring, reorganization, reborn, lots of re. Lots of machines and instruments were thrown in big containers. My friend felt sad seeing production- and lab equipment in the (once) million dollar level be cast out. Among them a remarkable instrument ,named " Micro Dynavision". Nobody knew who had bought the instrument and none had a clew what was the use of it. And there was no interest from anyone to have it. So, I got it. The cost is said to have been about 50,000 ...20 years ago. Now. The instrument is a wonder of mechanical precision, with numerous Loctite'd adjustment screws, three precision xyz digitizer bars (encoders), three light sources and a vision optic system with something that starts spinning when you switch on the Instrument. It's a heavy thing, weight about 50 kilograms. A computer belonged to it, but it was thrown before I got the machine. There are no servos, but you move the table with two micrometer. Has anybody ever seen this machine, and what is it made for?
