i wish i could get 100% reflectance at 90 degrees off of a piece of uncoated plain old glass...that would sure make life much easier not having to deal with all of those nasty coatings come again???
edit...for all practical purposes normal incidence is generally used for lenses in most applications...(so yes I misspoke in the essence of not wanting to type a lot, )
