Greetings all, I'm one of the "silent" members. But now I have something to offer.
A company named Lambda Photometrics(lambdaphoto.co.uk) in GB, also as Polytec PI S.A(pi.phot@polytec-pi.fr)in France, have decided to sell their optical benches and related optical materials at a discount, as they have moved out of that aspect of their business. These items are only in Europe, so once again: location, location, location!
The company is called PI(Physik Intstrumente), in the USA.
This is just a thought, but if someone can benefit from this, all the better.
