A beam splitter or beamsplitter is an optical component that is used for splitting an incident light beam in two directions. Beamsplitters are used to separate the light by a ratio of power between transmitted and reflected beams but can also be used to separate polarization states or different wavelenths of light. There are two main types of beamsplitters, plate beamsplitter and cube beamsplitter and each has their own advantages. Some industries that use beamsplitters are interferometry, bio-medical, metrology, life sciences, microscopy, fiber optics, telecommunication, and quantum communication. OptoSigma offers a broad selection of plate and cube beamsplitters to meet virtually any application. Some examples include Thin Plate Beamsplitters, Dielectric Plate & Cube Beamsplitters, High Power Polarizing Beamsplitters, Broadband Polarizing Beamsplitters, Plate Polarizing Beamsplitter and Variable Beamsplitters. If one of our many catalog beamsplitters do meet your requirements, send us a request for a custom mirror.
Plate Beamsplitters are optical components used to split incident light at a designated ratio into two separate beams. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction: cube or plate.
Cube Beamsplitter is an optical device that splits a beam of light in two. It is a crucial part of many optical experimental and measurement systems, such as interferometers. In its most common form, a cube is made from two triangular glass prisms which are bonded or contacted together at their base.
Cube Polarizing Beamsplitters
Cube Polarizing Beamsplitter is an optical device that splits a beam of light in two. It is a crucial part of many optical experimental and measurement systems, such as interferometers. In its most common form, a cube is made from two triangular glass prisms which are bonded or contacted together at their base. In a polarizing beam splitter, the transmitted beam and the diverted beam will have orthogonal polarizations. If you input polarized light, then the relative amount of transmitted/diverted power will depend on the input polarization.
