A device for in situ real time monitoring of atomic and molecular fluxes by use Rayleigh scattering. The flux can be generated by an effusion cell during molecular beam epitaxy. The present device uses a coherent light source, such as a helium neon laser, a high precision mirror assembly capable of providing an effective number of reflections though the flux beam and an interferometer detector to track the changes in flux.
