Laser laser processing when what are the factors affect the results

A laser processing, laser laser output spot obscured



the laser beam after the galvanometer and field lens flare is short of, not round. Laser laser processing, the output of the planes and fixed clamp and vibrating mirror, not good, lead to laser through some vibration lens flare obscured, after field lens gathered on the frequency doubling piece of light spot is a circle, this also is likely to lead to the effect is not uniform.



there is a situation in which the galvanometer deflection lens there is damage, when the laser beam through the lens damage area, can't reflect well. Therefore, laser beam through the lens damage area is inconsistent with the lens without damage area laser energy, all action on the data of laser energy is different also, and then make the engraving effect is not uniform.



2, selects the partial JiaoBiao moment must scale the content of the



gathered because each mirror has a corresponding scale, depth of focus and choose against focus method can simply lead to large-scale engraving pictures, marginal in the depth of focus point scale or beyond the depth of focus, so it is simple the effect of inhomogeneity. Therefore, the method of partial JiaoBiao moment that laser energy must be considered.



3, the machine is not set, the laser vibration lens or a mirror lens with parallel processing platform is not due to no levels, can lead to laser laser processing laser beam after field lens reaches the extent of the inconsistency on the processing objects, all the energy of the laser falls on the processed objects are not consistent energy density, at this point in the effect of heterogeneous data.



4, thermal lens



when laser laser processing laser optical lenses ( Refraction, reflection) When the lens fever causes slight deformation. This deformation can make the laser focus to rise, shorter focal length. If the machine is fixed, adjust the distance to the focus, the laser after a period of time, due to a thermal lens makes effect on the data of the laser energy density change, and then results in uneven engraving effect.
