beamsplitter
Optical path divider
A beamsplitter is an optical device that divides a beam of light into two separate beams, typically by transmitting part of the light while reflecting the rest.
Beamsplitters are essential components in interferometers, cameras, projectors, and laboratory optics: The laser passed through a beamsplitter to create two identical reference beams.
