[Rollei] Do it yourself circular polarizer

[Don Williams <dwilli10 >]

Edmund Optics is selling 2X2 quarter wave plates at $11.00.

If you have a cheap linear polarizer and the tools to open it you can slip 
one of these in, set to 45 degrees from the plane of polarization and end 
up with a circular polarizer.  Not sure but it might require some optical 
cement to really make it fool-proof.

Things like this can be done because I have done it.  I made some glass 
filters by sandwiching Kodak gels between two thin sheets of glass I got 
from the Old Edmund.  I did have a little advantage because I had easy 
access to a vacuum system and could take all the air out before doing the 
assembly.
