Excerpt from http://www.schneideroptics.com/filters/mc.htm
"B+W polarizers are available with optional multi-coating: the nature of
polarization renders the single anti-reflection coating unnecessary."
I found very interesting second part of this statement. Strangely, top
of the line of B+W filters recommended by Schneider for professional use
(Kaesemann version) is without any coating at all.
