The laser beam expander is a lens assembly that can change the diameter and divergence Angle of the laser beam. The laser beam emitted from the laser has a certain divergence Angle. For laser processing, only by adjusting the beam expanding mirror to make the laser beam collimated (parallel) beam, can the convergent mirror be used to obtain small high-power density spots. In laser ranging, it is necessary to improve the collimation of the laser to the maximum extent through the beam expanding mirror to obtain the ideal long-distance measurement effect.
According to the optical principle, the product of the optical diameter at both ends of the beam expanding mirror and the corresponding beam divergence Angle remains unchanged, that is, when the beam diameter is larger, the beam divergence Angle is also reduced with the corresponding magnification, which is the main feature of laser beam expanding. In laser focusing applications, the smaller the divergence Angle of the laser beam, the better the focusing effect. Therefore, the beam expanding mirror is mainly used in the field of beam expanding, reducing the optical divergence Angle and reducing the diffraction effect.
