Background technology
Laser marking compares traditional silk screen printing process, high with production efficiency, beats that to carve effect good, and marking content will not take off
The advantages such as color, because increasing product uses laser marking technique currently on the market.According to the difference of input light source wave band,
Current common various metals, nonmetallic materials can be marked with using laser marking technique.
The principle process of laser marking is：Laser produces energy source, by optical fiber or direct air dielectric transmission to sweeping
Mirror is retouched, by corresponding computer programme-control scanning mirror, so that control light curb correct direction to scan, then after focus lamp is focused in fact
Existing marking.In the process, because the light source of laser output is typically below diameter the 4mm even tiny light of a few tenths of a mm
Spot, this tiny hot spot is unfavorable for scanning mirror precise control, and small light spot energy density is too high to be also possible to burn out back end-mirror,
And because there is certain angle of divergence, final focusing effect is also undesirable.In order to solve above-mentioned Railway Project, at present in big portion
Divide laser marking field, be almost required for beam expanding lens, it is typically mounted between laser light-emitting window and scanning mirror, and it is acted on
In expansion of laser light light beam, improve beam quality, reduce laser diverging, so as to optimize whole light channel structure.Beam expanding lens is mainly logical
Specific curvature design is crossed, so that changing spot size after light path is reasonably reflected, reducing light extraction diverging.In this process
In, the spacing between two panels eyeglass is even more important.The fixed monocular tube beam expanding lens being substantially in current industry, current city
Conventional individual layer lens cone type beam expanding lens on field, it is assumed that the spacing on Theoretical Design between two eyeglasses should be X, but because
Can all there is the distance between error, final two eyeglasses during machining eyeglass, machining etc. can have the inclined of Δ X
Shifting amount, because being the design of monocular tube formula, so side-play amount cannot be eliminated and influence light-out effect.
