Beamsplitters Polarizing Non Beamsplitter - China

price: contact company for price

DeLn Beamsplitter products include Narrow Band Beamsplitter, Broadband

Beamsplitter, Beamsplitter Cube, Non-Polarizing Beamsplitter Cube,

Polarization Beamsplitter Cube, Penta Prism Beamsplitters, Lateral

Displacement Beamsplitters, etc.

1.Polarizing Beamsplitters are used to split unpolarized light into two polarized parts. And often used in semiconductor or photonics instrumentation to transmit p-polarized light while reflecting s-polarized light.

2.Non-Polarizing Cube Beamsplitters consist 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 hybrid coating allows the transmission and reflection of S- and P-polarization states to be within 6% of each other.
