Narrow Band Beamsplitter Cube

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.

You may refer to this page (http://www.pmoptics.com/optical_glass.html) for material properties.
