Cube Beamsplitter, Non-Polarizing, 25.4 mm, 632.8 nm Laser Line

Laser Line Non-Polarizing Cube Beamsplitters

The 10BC16NP.4 Laser Line Non-Polarizing Cube Beamsplitter is a 1.0 inch (25.4 mm) cube beamsplitter optimized for the 632.8 nm laser line. Our laser line non-polarizing cube beamsplitters provide true 50/50 beam splitting without altering the beam polarization, with the s- and p-polarized components matched to within 3%.
