Beam splitters are classified into several types of light sources

Beam splitters are classified by construction (plate, cube, pellicle, polka dot) and by function (standard, non-polarizing, polarizing, dichroic). Construction determines ghosting, damage threshold, and form factor. Function determines how polarization and wavelength are. 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. A beam splitter (or beamsplitter, power splitter) is an optical device which can split an incident light beam (e. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux). It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. It is also possible to combine the separated beams. Types of Beam Splitters 2. They are found in different configurations and can be used in multiple applications.
