What is the function of a beam splitter?

The function of a beam splitter is to divide a beam of light into two or more separate beams. This optical device utilizes the principle of partial reflection and transmission, which allows it to direct portions of the incoming light to different paths. Beam splitters are commonly used in various applications, such as in lasers for interferometry, microscopy, and even in fiber optic communication systems to manage light signals.

Understanding the function of a beam splitter highlights its significance in optical systems where precise manipulation of light pathways is essential. This capability to split light is crucial in various experimental setups and imaging techniques where multiple paths of light need to be utilized for analysis or enhancement of results.
