The diameter of laser beam is proportional to the focus length.
Smaller the focus length cause smaller laser spot, better engraving effect will be;
Larger the focus length cause larger laser spot, stronger the cutting power will be;
Under the same parameters, the engraving quality levels with different focus distant arrange as:38.1mm>63.5mm>100mm;
Cutting power with different focus distant arrange as:38.1mm<63.5mm<100mm; You can make selections according to the actual processing requirements
