Non-Polarization Beamsplitter Cubes (NPBS) is designed to split the incident light at a specific percentage that is not sensitive to the polarization state, and the hybrid coating is also insensitive to the angle of incident light. The identical spectral characteristic can be kept at a broad spectral range, which makes it fit for tunable lasers. The hybrid coating has a certain of absorption, and NPBS is not suitable for the high power lasers.

Hangzhou Shalom EO offers the Non-Polarization Beamsplitter Cubes (NPBS) with a series of wavelength band: 450-650nm, 650-950nm, 900-1200nm and 1200-1600nm. Our NPBS are low polarization dependence of the metallic-dielectric coating, the transmission and reflection for S- and P- polarization states is within 5% of each other.
