That's where we send all our Zeiss Ophthalmic stuff for repair and servicing. I figure it's worth asking the question, but don't expect it to come cheap
Quote: "There is a theory which states that if ever, for any reason, anyone discovers what exactly the Universe is for and why it is here it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another that states that this has already happened.”... Douglas Adams 1952 - 2001
