Non-Polarizing Cube Beamsplitters (NPBS) Optical Lens

La description

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、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 Cubes 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.
