mr. WJC! dont response to my thread's if your answers not offer a solution and attached with nonsense articles. you are not assist to solve or participant dialogue on issues of optics this forum! thanks!
Mr. Publin,
Based on your rudeness to me, and ignorance of optics, I was prepared to respond in kind. However, I deleted that post, repented, and will try another way. Binastro, being a nicer guy than me—although he obviously can’t spell “humor” 8-P —answered you with thoughtful kindness. I was prepared to meet you with the old saying,
“If you mess with the bull, you’ll get the horn.”
In regard to that “nonsense” article, EVERY word in it was true. EVERY word in it
could have been valuable to you—whether YOU understood the humor or not—because it came from one who, after a lifetime in professional optics, is absolutely mystified, and sometimes angered, by those who feel some sick need to say something about optics—for which they are not qualified—that costs our neighbors time, money, and frustration. Don’t you think after 45 years in optics engineering, repair, and collimation that if Hydrogen Peroxide were something to be used in cleaning optics I would have heard of it? What about InstaClear, LensLuster, Kodak this, Vivitar that, Bausch & Lomb something else, and, hey, Zeiss cleaner has an emulsifier.
Years ago, there was a fellow who knew better than me (because he had been speaking with his local optical guru) how to attach his prisms at the corners. He learned from the opinionated—but inexperienced—how “Superglue” would be “so much better” than the adhesive I used. (I had only been in optics 37 years at that point.) I warned him about superglue’s “outgassing”—something of which he was not aware and had never heard of. And since HE hadn’t heard of it, I must have been making it up ... right?
So, he used Superglue. A few minutes later, on noticing images in that side of the binocular were totally milky, he came to me to bail him out. But with the outgassing coating ALL the exposed surfaces on that side—and being quite resilient even to acetone—I had to tell him that what would have cost him nothing, had he followed my advice—the REPAIR would now cost 3 times what his binocular was worth ... new, because of the tremendous amount of work involved. Was it MY fault that he chose to listen to a big-mouthed but inexperienced friend? Do you think he thought of that on his way to the dumpster with his paperweight shaped like a binocular?
Publin, I am, perhaps, just more human than most, but I can’t help growing frustrated at the absolute ABSURDITIES associated with cleaning optics and so many other things related to optics in general and binoculars in particular.
— NO, acetone doesn’t remove lens coatings. Abrasion, and coatings deposited at too low a temperature cause the problem. That’s why professionals leave jabber jawing to the opto-wannabes while they get on with cleaning optics ... as they have done for decades. Acetone is routinely used by TeleView Optics, Lawrence Livermore Labs, and many other places where EXPERIENCED optical professionals work.
— NO, acetone is not a carcinogen; it’s manufactured in our bodies.
— NO, Windex need not be avoided, although the “original” Windex sold in store, today is NOT the original 1933 Windex glass cleaner and contains chemicals to make it a “household cleaner.” The original (Harry Drackett) formula is offered in the “nonsense” article.
I don’t hold you accountable because English is not your first language. Please don’t hold me accountable because it
IS mine.
I thought you came to Bird Forum because you wanted to know more. Yet, you needn’t worry, I will no longer interfere with “YOUR” thread. :cat:
