These are used as beam splitters in many optical instruments.
Detect these photons after they have been mixed together using a beam splitter.
A hole mirror or a beam splitter are options to collect a return signal.
The prism can therefore be used as a polarizing beam splitter.
Inside the camera, a beam splitter separates the light from the scene into red, green and blue light.
Note also the precise orientation of the beam splitters.
A wide laser or light beam is first shot at the beam splitter.
A beam splitter separates the light into reference and measurement beams.
The Fresnel reflection from the first surface of the mirror acts as a beam splitter.
Next, as shown in the bottom diagram, a second beam splitter is introduced at the top right.
