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.
