Non Polarizing Beam Splitter

TECH SPEC NON-POLARIZING VISIBLE AND NEAR IR HYBRID BEAMSPLITTERS

The low polarization dependence of the metallic/dielectric hybrid coating allows the trans-mission and reflection for S and P Polarization states to be within 6% of each other. These beamsplitters are also spectrally flat across the specified flatness also reduces the effects due to changes in the angle of incidence or converging/diverging beams. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one. A broadband antire-flective (BBAR) coating has been applies to each face of the beamsplitter in order to pro-duce maximum transmission efficiency. Two different wavelength ranges are available. 400-700nm and 700-1100nm.
