Product Description:
A beam splitter is an optical device to split a light beam into two orthogonal beams. It is made from a pair of precision high tolerance right angle prisms which are glued together. The ratio is stated for unpolarized light. A beamsplitter cube, tailored for a specific range of wavelengths, can ensure the appropriate performance.
