beam splitter

The beam splitter splits the light path to allow a video camera, digital camera, or an assistant scope to be attached to the microscope.Beamsplitters are optical components used to split incident light at a designated ratio into two separate beams. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction.The beam splitter in a trinocular microscope controls the amount of light that travels up to the camera on the trinocular port. When light enters the microscope, it is split into two paths – one path goes to the eyepieces, and the other path goes to the camera.
