Vignetting
Optical cropping of the image caused by the components in the projection lens. This can happen if too much offset is applied when
positioning the image using the lens mount.
ZScreen
A special kind of light modulator which polarizes the projected image for 3D viewing. It normally requires that images are projected onto a
silver screen. The ZScreen is placed between the projector lens and screen. It changes the polarization of the projected light and switches
between left- and right-handed circularly polarized light at the field rate.
