T-BPD508-FS - Polka Dot Beamsplitter, Ø2", UV Fused Silica
T-BPD508-FS - Polka Dot Beamsplitter, Ø2", UV Fused Silica
These Polka Dot Beamsplitters are made from UV Fused Silica (UVFS) and provide high transmission over the 250 nm - 2.0 µm spectral range. They can be used from 0 to 45° AOI with only negligible changes to the reflected and transmitted intensity. Light should be incident on the aluminum-coated side to maximize the reflected intensity.
