Does this type of polariser work with normal polarising glasses? $64.00 per 1 inch clear
aperture is quite expensive, how does this take the heat ?

Where could I get some for a test?

<PRE>&nbsp; Dichroic Sheet Polarizers have an Extinction ratio
of 10,000:1 for White light!&nbsp; It would seem to me though,
even if you were to use a set of these on the output of the&nbsp;
projector lenses and had matching sets for your "glasses"
you would still see some ghosting because of the screen
buggering up the polarization on the way back to you.&nbsp; Any
comments?&nbsp; One of these polarizers cost $64.00 for a 1"
clear aperture size.
