I would like to know more about lens coatings, phase correction and other factors that affect binocular performance.
Does anyone know a website that has a good semi-technical treatment of these interesting optical terms ?
In the areas of lens coating and baffling, the lion's share of development occurred in the photographic realm, but are applicable to binoculars (and refracting telescopes, too).
