Beamsplitter, Non-Polarizing, 25.4 mm Diameter, 830 nm Laser Line
Model: 10B20NP.28
Product Series Overview
Laser Line Non-Polarizing Plate BeamsplittersThe 10B20NP.28 Laser Line Non-Polarizing Beamsplitter is insensitive to the polarization of an incoming beam. Unlike broadband dielectric beamsplitters, which are extremely polarization sensitive, this beamsplitter provides a true 50/50 split regardless of the incoming polarization. The polarization components are matched to within 5%. Near zero absorption in these dielectric beamsplitters results in true 50/50 split of the beam and high damage threshold. They are especially useful for higher power applications where cemented cube beamsplitters may fail. This 25.4 mm diameter beamsplitter is manufactured using a high-precision BK 7 substrate to minimize wavefront distortion. A slight wedge in the substrate helps eliminate back reflections to the laser. The front surface is coated with a multilayer all-dielectric non-polarizing beamsplitter coating optimized for 830 nm. The back surface is coated with a multilayer dielectric antireflection coating to minimize surface reflection losses and eliminate ghost images.
