For example, beam splitters are required for various interferometers, autocorrelators, photo cameras, projectors and laser systems. The wide range of applications implies widely varying requirements, which can be fulfilled with different types of splitters. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. This division allows for the simultaneous analysis or utilization of the light's properties along two separate paths. Beamsplitters are often classified according to their construction: cube or plate. A beam splitter (or beamsplitter, power splitter) is an optical device which can split an incident light beam (e. When a light beam encounters these cubes, half of it penetrates the glass, while the other half gets reflected.
