New Article: Reflections on reflections. Coatings: The Most Important Part of Your Lens
We are posting another article written by Roger Cicala at LensRentals.com.
Todays article touches on coatings. Their history, and their importance in optical design. As always, it’s pretty informative..
So How do Coatings Work?
It’s pretty simple to explain if you have a Ph. D. in optical physics and speak higher order mathematics. I don’t, so I’ll just have to explain it to you like it was explained to me (and I’ll put some references at the end of the article for those of you who want to double check the Trig and Calculus formulas). Basically, though, there are three types of coatings, each working in a different way. The first two types can be combined with each other to improve their effectiveness; the third type (nanocoating) is so effective it doesn’t need any help.
