11. The dichroic beam splitter controls which wavelengths of light go to their respective filter. 12. A laser pulse is first split using a beam splitter into two different laser lines. 13. A laser is divided into two beams by a Beam splitter tilted by 45 degrees. 14. In Fig 6 the integration in the beam path behind a beam splitter is shown. 15. The Fresnel reflection from the first surface of the mirror acts as a beam splitter . 16. Note also the precise orientation of the beam splitters . 17. Various methods of phase or polarization control can be used such as interferometers and beam splitters . 18. The relative probabilities of transmission and reflection are determined by the reflectivity of the beam splitter . 19. This can be seen most clearly when we write the two-mode beam splitter transformation in matrix form: 20. To do this measurement ( as our article points out ) you need a beam splitter interferometer.
