Linear Polarizing Filters for Projectors

These are two (2) plastic backed polarizing filters 3" x 3", for attaching to any 2 projector system for projecting stereo images.  For projectors with larger, long throw or zoom lenses we offer 4" x 4" polarizers and 6" x 6". Both these will work with all our linear 3d polarized glasses.  These are 45, -45 degree polarizers. These are heavy duty heavy gauge plastic and will not bend.  Attachment will depend on your projectors (no mounting gear is included).  Be careful not to mount these polarizers too close to your lenses as excessive heat will damage or crack the polarizers.  Projectors vary in heat generation so please monitor when using.  Please cover the entire surface of the filter with the projected light to eliminate hot spots. Try our filter holder and heat absorbing filters to extend the lifetime of your polarized filters! Polarizing filters are not returnable.
