Hello
It has been a few years since I worked with one. I believe they call it active polarization. The z screen mounts in front of the lenses, and viewers wear passive polarized glasses. Light output from your projector is cut about in half.

The z-screen more than cuts the light in half, and the glasses cut it in half again. It'll make for a very dim image.
Unless you plan on having more than 3-4 viewers, why not just go with active glasses? Light output isn't much better, but it sure is easier putting a few pairs of glasses on than it is having to swing a big expensive polarizer in front of the projector.

I like this part in the brochure:
Although weaker in light output, a CRT projector
allows for the highest resolution large screen
images, with unparalleled visual fidelity.
