- A beam splitter is an optical device that divides a beam of light into two or more separate beams. The device works by reflecting a portion of the light and transmitting the rest through the surface of the splitter.
- Beam splitters are commonly used in a wide range of applications, including microscopy, interferometry, and laser technology. The splitters can be used to separate or combine light beams, create interference patterns, or produce multiple images of a single object.
