    Optical Coating Laboratory, Incorporated makes a proprietary anti glare
coating for CRT manufacturers.  It works by coating a layer above the glass
such that the layer is 1/4 wavelength at the frequency of interest and is
reflected back from the glass/coating layer...voila, destructive cancellation.
Since the layer has an optical refractive index of ( n ** 1/2 ???) where n
is the glass r. i., the image coming from the CRT phosphour is not diffused...

     First, if you are willing to go to a LOT of trouble, the CRT which was
put in your terminal is ** Probably ** available in an OCLI version.  Second,
OCLI makes their neat stuff in sheet stock which they would be glad to cut
up for you to the right size.

   P.S.  Be cool with these people, i.e. they are OEM's, not your
   basic ComputerWimp dealer . . .
