Non-Polarizing Cube Beamsplitters

Non-Polarizing Cube Beamsplitters also called NPBS Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces.The cemented face of one prism is coated. Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection could be designed to 10%, 20%, 30%, 40%, 50%, etc.

2.1、What is a Non-Polarizing Beamsplitter Cubes?

Non-polarizing Beamsplitter Cube consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic-dielectric coating allows the transmission and reflection for S- and P- polarization states to be within 5% of each other. This means that they will not change the state of polarization of the incident beam. We offer both broadband and single wavelength non-polarizing cube beamsplitters (NPBS). An antireflective coating has been applied to each face of the beamsplitter in order to produce maximum transmission efficiency for the appropriate wavelength range.


2.2、How does a Non-polarizing beamsplitter Cube work?

These cubes split the energy with minimal polarization sensitivity. The polarization states are about the same for the entrance and exit beams. Broadband Non-Polarizing Beamsplitter Cube’s hybrid coating has certain absorption but minimal polarization sensitivity. Due to the metallic nature of the hybrid coating, those cubes are not intended for use with high power lasers.
