5 mm thickness? How large is the diameter?http://de.wikipedia.org/wiki/Wollaston-Prisma

I'm looking for apertures between 10mm and 20mm. A Wollaston might do

I am looking for a vendor who can supply me with a polarization
separating prism pair.  By this, I mean a pair of thin prisms
(preferably cemented together) that will split (in angle) the e and o
rays.  This is to be used for an imaging application in collimated
space with the splitting being only a mRad or two.  The prism pair
should be thin (less than 5mm).

Anyone know of an off the shelf source or a company (preferably but
not necessarily in the United States) that can make such an item?

What about a DIC prism from one of the major microscope
manufacturers?  The divergence is fairly small, AFAIK.  They are stock
parts.

Why not put a walkoff plate at the pupil?  Those you can get for
boxtops, iirc.

What is a walk off plate?

Just a random chunk of calcite or birefringent polymer, whose optic axis
doesn't lie in the plane of incidence.  The O ray goes through as
specified by Snell's Law, but the E ray 'walks off' sideways in the
process--its path lies between the O ray and the optic axis.  Once they
come out the other side, they're back to being parallel, but with a
lateral shift.

Doing that at the pupil is equivalent to your device at the image.  (In
fact I think the CCD devices are walkoff plates and not Wollastons, but
I don't know for sure.)
