Non polarizing beam splitter.
Non polarizing beam splitter.
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.
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.
We have set your country region to united states.
Broadband non polarizing beamsplitters with metal hybrid dielectric coatings.
Custom facets chamfers notches and other features are also available.
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.
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.
A non polarizing beam splitter is used to split light independently of polarization state.
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.
Broadband and chromatically neutral.
You can change this selection at any time but products in your cart saved lists or quote may be removed if.
These filters have very small polarity dependences typically about 3 6.
Even power split ratio insensitive to polarization.
Tech spec non polarizing visible and near ir hybrid beamsplitters.
Non polarizing plate beamsplitters thorlabs offers a wide variety of plate beamsplitters.
Our broadband non polarizing hybrid cube beamsplitters are ideal for use with multiple lasers or tunable sources.
Non polarizing beam splitter cubes can be made by refining the design normally via a multilayer coating between 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.
Our non polarizing beam splitters have applications in laser beam manipulation and interferometry and we offer both plate and cubic options.
Thorlabs offers non polarizing cube beamsplitters for visible 400 700 nm nir 700 1100 nm and ir 1100 1600 nm light.
