Beam splitter

A beam splitter is an optical device that divides a beam of light into two parts. It works by reflecting some of the light while allowing the rest to pass through. This is useful in various applications, such as in lasers, cameras, and optical instruments, where precise light manipulation is needed. By controlling how much light is reflected and transmitted, beam splitters help scientists and engineers explore and measure properties of light, enabling technologies like holography and quantum computing. Essentially, they are key tools in the field of optics that help manage light effectively.
