Cube beamsplitters
A line of low-polarizing cube beamsplitters are made from a hybrid metallic and dielectric coating, which produces an even split in intensity with minimal absorption and minimal polarization. The cubes are available at popular wavelengths through the visible and IR from 400 to 700 nm and from 600 to 900 nm; some broadband models are available in 400- to 1100-nm and 800- to 1600-nm versions.
