A Non polarizing beamsplitter cube is a kind of beam splitter that slip light using a hybrid metallic-dielectric coating that is insensitive to polarization. It is often used in low-power applications since the metal content in its coating implies high thermal absorption.
Hangzhou Shalom EO offers a series of non polarizing beamsplitter cubes of various off-the-shelf and custom bandwidths, incuding 450-650nm, 650-950nm, 900-1200nm, and 1200-1600nm.
