I wonder where you get that info. I happen to work with optics at one of those institutions and can assure you neither I nor anyone else I have seen use windex to clean optics. We do use the windex foaming glass cleaner to clean non-optical surfaces but never anything in a light path. Interestingly I also remember recently you claimed that acetone was the optics cleaner of choice at that same list of institutions.
Hi has 530:
“I wonder where you get that information.”
I got it from 50 years in the optics industry, 12,000+ binocular repair and collimation jobs, firsthand experience dealing with optical engineering and repair, being a Chief Opticalman for the Navy, being friends with optical engineers, corporate heads of optical sales and repair companies in the United States and Europe, respected authors of optically-oriented books, as well as the movers and shakers who frequent BirdForum, and I know the difference between popular, ego-stroking bull crap and rational thought. I know that BF is built on OPINION. However, I don't play that game.
Next you say:
“I happen to work with optics at one of those institutions and can assure you neither I nor anyone else I have seen use windex to clean optics.”
I have never been ashamed of who I have done optics for: the Navy, the Navy Reserve (where I was selected chief optical tech for SIMA San Diego, Puget Sound Naval Shipyard (where I was also a test director), Fort Lewis (now Lewis-McChord), US Department of Defense, and 21 years at the late Captain’s Nautical Supplies in Seattle.
Thus, “I happen to work with optics at one of those institutions AND CAN ASSURE YOU NEITHER I NOR ANYONE ELSE I HAVE SEEN USE WINDEX TO CLEAN OPTICS.”
I would be more impressed if you would tell us the name of that company, the optical title you held, and the length of time you were in that role. Be advised however, that the credentials of Ph.Ds. don’t impress me if I know they are wrong. That is why I was invited to speak on Collimation vs Conditional Alignment to the optical Ph.Ds. at SPIE’s 2012 Photonics West in San Diego. (Attachment 1)
But then, as Mark Twain said:
“Truth has no defense against a fool determined to believe a lie.”
I would appreciate being your friend. But I have a job to do. In order to do it, I have to keep my credibility intact. So, if you persist in nipping at my heels, you may ultimately wish you hadn’t, for I have only scratched the surface on sharing my credentials and associations in the optical industry.
