Non Polarizing Beam Splitter

Custom facets chamfers notches and other features are also available.

Non polarizing beam splitter.

Non polarizing beamsplitters ideal for interferometry life science instrumentation or laser beam manipulation systems are available at edmund optics. Broadband non polarizing beamsplitters with metal hybrid dielectric coatings. Tech spec non polarizing visible and near ir hybrid beamsplitters. 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.

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. The low polarization dependence of the metallic dielectric hybrid coating allows the trans mission and reflection for s and p polarization states to be within 6 of each other. You can change this selection at any time but products in your cart saved lists or quote may be removed if. Even power split ratio insensitive to polarization.

These filters have very small polarity dependences typically about 3 6. Our non polarizing beam splitters have applications in laser beam manipulation and interferometry and we offer both plate and cubic options. 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. Chat email.

Non polarizing beam splitter cubes can be made by refining the design normally via a multilayer coating between the prisms. Our broadband non polarizing hybrid cube beamsplitters are ideal for use with multiple lasers or tunable sources. Uv fused silica 250 1700 nm ir fused silica 900 2600 nm calcium fluoride 1 8 µm and zinc selenide 1 14 µm covering the uv mir wavelength range. 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.

Beamsplitter cubes are available with split ratios of 30 70 50 50 or 70 30 and in sizes of 5 mm 10 mm 20 mm and 25 4 mm. Broadband and chromatically neutral. Thorlabs offers non polarizing cube beamsplitters for visible 400 700 nm nir 700 1100 nm and ir 1100 1600 nm light. Non polarizing plate beamsplitters thorlabs offers a wide variety of plate beamsplitters.

The substantial angle of incidence will naturally introduce a substantial polarization dependence but there are certain design principles which can be used to minimize such effects at least within some limited optical bandwidth. Incoming beams are both transmitted and reflected 45 with the s and p polarized components matched to within 10.
