Changed the formula on the page to its full form including a sin(theta) as the small angle approximation made for angles <20 degrees before wasn't valid. Oct 23, 2009 —Preceding unsigned comment added by 82.9.107.87 (talk) 12:23, 23 October 2009 (UTC)Reply

Merge?

Latest comment: 9 years ago3 comments2 people in discussion

Are there any non-thin film interference filters? If not, it seems like these should be merged into or as a section of Thin-film interference. Dspark76 (talk) 18:24, 6 May 2014 (UTC)Reply

The name "interference filter" is the technical name of a specific scientific apparatus that happens to use interference to accomplish filtering. The term shows up in articles published in scientific journals of all sorts, describing some experimental setup. A "stealth fighter aircraft" is also uses thin-film interference (at radar wavelengths) to provide stealth capability, but you would not propose merging that article into thin-film, would you? I'd recommend no merge. 67.198.37.16 (talk) 16:00, 26 September 2015 (UTC)Reply

Might make sense to merge into dichroic filter, though, although dichroic filter seems to cover broader uses than optical benches. 67.198.37.16 (talk) 16:14, 26 September 2015 (UTC)Reply
