Laser collimator is one of the core accessories of laser welding machine, laser marking machine, laser cutting machine, laser engraving machine and other laser equipment, collimator is for point light source, laser collimator is light from energy fiber, that is, a point light source with divergence angle, put this light source on the focus of the fiber collimator, the light emitted from the focus of the focusing mirror, after passing the collimator will become a parallel light. Laser collimators are used in various optical measurement systems, often used to collimate optical paths, so that divergent optical paths become parallel optical paths. In combination with different optics, beam collimation can be optimized for different measuring processes. In order to improve the fiber coupling efficiency and reduce the beam divergence angle, the fiber port needs to be equipped with a fiber collimator. After passing through the collimator, the area of the focused spot is twice as large as the area of the point light source just coming out of the energy fiber, and the energy density is 1/2 of the original. High beam collimation After being adjusted by the fiber collimator, the divergence angle of the beam does not exceed 2°.
