Optical Beamsplitters Thorlabs offers a wide range of optical beamsplitters. Our plate beamsplitters have a coated front surface that determines the beam splitting ratio while the back surface is wedged and AR coated in order to minimize ghosting and interference effects.
An unpolarized beam is split into two orthogonal, linearly polarized components. P-polarized light is transmitted, while s-polarized light is reflected, both with negligible absorption. The extinction ratio is better than 1000:1 for beamsplitter made with N-BK7 glass, and better than 100:1 for beamsplitter made with UV fused silica. Fourier modal method (FMM) is applied for the rigorous evaluation of non-paraxial diffractive beam splitters, which are initially designed by using IFTA and thin-element approximation.

At the same time, four edge filters were designed, and an experimental study on the beam multiplexing of diode laser arrays was carried out. Second, two beams with different polarization states were composited using a half wave plate and a polarizing beam-splitter prism. After that, the beam focusing system was designed. A new reflecting polarizing beam splitter (RPBS), based on a metal–multilayer dielectric grating (MMDG), was designed using rigorous coupled wave analysis method and a genetic algorithm. The RPBS reflects the TE wave in the −1st order and TM wave in the 0th order for 800 nm.

Non-polarizing beam splitter cubes can be made by refining the design, normally via a multilayer coating between the prisms. 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. Mar 05, 2020 · These cubes are designed to be used with the transmitted beam, which offers an extinction ratio of T P:T S > 1000:1. The reflected beam will only have an extinction ratio of roughly 20:1 to 100:1, depending on the beamsplitter. Thorlabs offers polarizing beamsplitter cubes in 5 mm, 10 mm, 1/2" (12.7 mm), 20 mm, 1" (25.4 mm), and 2" (50.8 mm) sizes.
