Polka Dot Beamsplitter, 25.4 mm Diameter, 250-2500 nm

The PDOT-1 Polka Dot Beamsplitter is a 1.0 inch (25.4 mm) diameter, 50/50 polka dot beamsplitter optimized for 250-2500 nm. Our 50/50 Polka Dot Beamsplitters are UV fused silica substrates coated with aluminum and SiO protective overcoat in a polka dot pattern. Optimized for white light illumination applications, they provide two unique advantages over traditional dielectric beam splitters: they are neutral over the wavelength range of the fused silica substrate and the aluminum coating, and they are not sensitive to angle of incidence changes.
