Polarizing Beam Splitter Cube

The beam that passes through the cube deviates greatly in the plane parallel to the base of the cube.

Polarizing beam splitter cube.

Beam splitting polarizers split the incident beam into two beams of differing linear polarization. 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. Laser line polarizing cube beamsplitters provide efficient narrowband polarization for higher power lasers. We bought polarizing beamsplitter cube pbs054 at thorlabs 18 sep 2013 web order acknowledgement web n6w421935.

488 nm to 1550 nm polarization. Their extinction ratio is better than 1000 1 and they are recommended for use in pulsed laser systems and for purifying the polarization state in multimode lasers. Many beam splitters have the form of a cube where the beam separation occurs at an interface within the cube figure 2. Non polarizing cube beamsplitter 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.

We have installed it into the optical scheme and discovered some strange behavior. Number on the package w006430. In its most common form a cube it is made from two triangular glass prisms which are glued together at their base using polyester epoxy or urethane based adhesives the thickness of the resin layer is adjusted such that for a certain wavelength half of the light incident through one port i e face of the cube is reflected and the other half is transmitted due. For many common beam splitting polarizers however only one of the two output beams is fully polarized.

Negligible absorption for true 50 50 beamsplitting. No phase shift between s p pol. 20 to 80 damage threshold. Such a cube is often made of two triangular glass prisms which are glued together with some transparent resin or cement.

All varieties of beam splitters are available in a wide selection of sizes and glass types with tight surface quality angles dimensions flatness and transmitted wavefront requirements. Laser line non polarizing cube beamsplitters. S p unp clear aperture.

For an ideal polarizing beamsplitter these would be fully polarized with orthogonal polarizations. R 0 25 reflectance. Broadband non polarizing beamsplitters with metal hybrid dielectric coatings. 85 of diameter edge bevel.

Custom facets chamfers notches and other features are also available. 0 3 mm face width at 45 adhesion and durability. Cube beamsplitters non polarizing part code. The thickness of that layer can be used to adjust the power splitting ratio.
