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.
