It is widely used in power splitting, polarization separation, wavelength division multiplexing and other scenarios. Beamsplitters are optical components used to split incident light at a designated ratio into two separate beams. Pellicle beamsplitters provide excellent wavefront transmission properties while eliminating beam. The Laser Interferometer Gravitational-Wave Observatory (or LIGO) uses beamsplitters to detect gravitational waves, precision measurement systems depend on them, and high-end iPhones use them in FaceID. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux).
