Application[edit]

The examples shown here obviously related to some kind of lens. There is a link to this article from the entry for parabolic trough collectors. Does this acceptance angle concept also apply to reflecting solar concentrators, or only lens-type ones ?Eregli bob (talk) 08:00, 1 May 2011 (UTC)[reply]

I expect that it does. The imaging properties of lenses and mirrors are much the same.--Srleffler (talk) 01:27, 2 May 2011 (UTC)[reply]

Concentration acceptance product (CAP)[edit]

The Concentration acceptance product (CAP) section is meaningless, since it does not state whether it is talking about linear focus or point focus systems. The answer is different: the product is squared for a point focus and not squared for line focus. Geoffrey.landis (talk) 03:14, 8 June 2015 (UTC)[reply]
