American Polarizers (Reading, PA) has introduced glass 3D circular polarizing filters for use with dual projection systems. API filters feature a range of sizes up to 14" x 20". Tight control of transmission characteristics gives the filters low ghosting properties when used with high-light-output projection systems of up to 30,000 lumens. Anti-reflective coatings on both sides enhance light transmission properties. Standard axis configuration is 0°/90°, but nonstandard axis configurations can be customized whether for circularly or elliptically polarized filters.
