AR coatings
I moved the line you added to Anti-reflective coating to a new History section.

We could use more information on what exactly Alexander Smakula invented. It's not clear how his invention fits in with the other limited history information that was already in the article. Other sources put the first invention of interference-based coatings in the 1930's, and the first index-matching coatings in the 1880's. --Srleffler (talk) 02:36, 6 January 2013 (UTC)
