Polarizing Beam Splitter Cube

Number on the package w006430.

Polarizing beam splitter cube.

Such a cube is often made of two triangular glass prisms which are glued together with some transparent resin or cement. Many beam splitters have the form of a cube where the beam separation occurs at an interface within the cube figure 2. Custom facets chamfers notches and other features are also available. The beam that passes through the cube deviates greatly in the plane parallel to the base of the cube.

S p unp clear aperture. We have installed it into the optical scheme and discovered some strange behavior. 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. 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.

Beam splitting polarizers split the incident beam into two beams of differing linear polarization. 100 mj cm 2 10 ns pulse standard wavelengths. No phase shift between s p pol. Laser line polarizing cube beamsplitters provide efficient narrowband polarization for higher power lasers.

For an ideal polarizing beamsplitter these would be fully polarized with orthogonal polarizations.

R 0 25 reflectance. A beam splitter cube which may be polarizing or non polarizing.

Even power split ratio insensitive to polarization. Cube beamsplitters non polarizing part code. 0 3 mm face width at 45 adhesion and durability. For many common beam splitting polarizers however only one of the two output beams is fully polarized.

Laser line non polarizing cube beamsplitters. Broadband non polarizing beamsplitters with metal hybrid dielectric coatings. 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. 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.

Negligible absorption for true 50 50 beamsplitting. 488 nm to 1550 nm polarization. 20 to 80 damage threshold. We bought polarizing beamsplitter cube pbs054 at thorlabs 18 sep 2013 web order acknowledgement web n6w421935.
