Rediffusion mirror professional processing spectroscope,

The amplifiers are the lens assemblies that can change the diameter and divergence Angle of the laser beam. From laser divergence Angle of laser beam has a certain, for laser processing, it is only through the adjustment of the beam expander make laser beam collimation (parallel) beam, to achieve a small high power density using the focusing lens flare; In laser ranging, it is necessary to improve the accuracy of the laser to achieve the desired long distance measurement. The diameter of the beam can be changed by the beam-expanding mirror to be used for different optical instruments; The distribution of asymmetric beams can be changed to symmetrical distribution and the distribution of light energy is more uniform.
