  • What are the uses of installing a beam splitter in a computer room

    What are the uses of installing a beam splitter in a computer room

    The most basic function of a beam splitter is to divide an incoming light beam into two or more beams with specific intensity ratios. One portion passes through the device while the other reflects off it, and the ratio between the two can be controlled by design. The resulting beams are directed along different paths, allowing a single light.
