T-BPD254-G - Polka Dot Beamsplitter, Ø1", B270 Glass
T-BPD254-G - Polka Dot Beamsplitter, Ø1", B270 Glass
These Polka Dot Beamsplitters are made from B270 glass and provide high transmission over the 350 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.
