BeamsplittersA beamsplitter is a type of optical component that is used to split a beam of light into two or more separate beams. Beamsplitters are commonly used in laser systems, where they are used to split the output of a laser into multiple beams that can be directed to different locations or used for different purposes. Beamsplitters are available in a variety of forms, including cubes, plates, and prisms, and can be made from a variety of materials, such as glass, plastic, or metal. The performance of a beamsplitter is typically characterized by its splitting ratio, which is the ratio of the power of the split beams to the input beam, and its wavelength dependence, which is the degree to which the splitting ratio varies with the wavelength of the light.
