Uv polarizing beam splitter cube.

Posted on september 28 2020 by sandra. We have installed it into the optical scheme and discovered some strange behavior. Polarizing cube beamsplitters offer a transmission of greater than 95 for p polarized light and a reflection efficiency of greater than 99 8 for s polarized light at designed wavelength each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse. Negligible absorption for true 50 50 beamsplitting.

The beam that passes through the cube deviates greatly in the plane parallel to the base of the cube. No beam displacement easy to mount mechanically durable high laser damage threshold options available for power or polarization separation. No phase shift between s p pol. Uv polarizing beam splitter cube.

Laser line non polarizing cube beamsplitters. Uv f silica cube polarizing beamsplitter 430 1105 m2ps. We bought polarizing beamsplitter cube pbs054 at thorlabs 18 sep 2013 web order acknowledgement web n6w421935. Even power split ratio insensitive to polarization.

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. Visible and near ir laser line polarizing cube polarizers. 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. Thorlabs 50 50 uv fused silica broadband beamsplitters which are available in ø1 2 ø1 25 mm x 36 mm and ø2 versions have a beamsplitter coating for the 250 450 nm range deposited on the front surface that has been optimized for a 45 angle of incidence.
