Broadband Polarizing Beam Splitter

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.

Broadband polarizing beam splitter.

50 10 standard diameter. An ultra broadband polarization beam splitter pbs with low excess loss el and a high extinction ratio er is proposed and demonstrated for the case with 340 nm thick silicon on insulator waveguides. We design and experimentally demonstrate a polarizing beam splitter pbs on a silicon on insulator soi platform based on an asymmetric directional coupler. 0250 in to 0 500 in thickness tolerance.

Providing exceptional image contrast and uniformity these beamsplitters are ideal for applications requiring large angular apertures and high throughput. 0 0 0 20 mm standard thickness. Designed for broadband applications techspec broadband polarizing cube beamsplitters offer a transmission of greater than 90 for p polarized light and a reflection efficiency of greater than 99 for s polarized light across the entire design wavelength range. Incoming beams are both transmitted and reflected 45 with the s and p polarized components matched to within 10.

A polarizing beamsplitter cube splits randomly polarized beams into two orthogonal linearly polarized components. Broadband polarizing plate beamsplitters consist of a thin layer of aluminum microwires adhered to a glass window. These beamsplitters are an alternative and economical substitute for ruled or holographic wire grid polarizers. Broadband and chromatically neutral.

10 5 laser quality r unp. Plate beamsplitters broadband 50 50 part code. Even power split ratio insensitive to polarization. 1 0 in to 4 0 in diameter tolerance.

An unpolarized beam is split into two orthogonal linearly polarized components. Broadband polarizing beamsplitter cubes. S polarized light is reflected at a 90 degree angle while p polarized light is transmitted. P polarized light is transmitted while s polarized light is reflected both with negligible absorption.

Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of the prisms. A dielectric coating provides long term stability. The asymmetric directional coupler consists of a regular strip waveguide and a sub wavelength grating swg waveguide. λ 10 633 nm surface quality.

Four broadband multilayer coatings are offered covering the 420 680 nm 620 1000 nm 900 1300 nm and 1200 1600 nm wavelength ranges.
