1In the laser marking machine, our common lenses are 50*50, 110*110, 160*160, 220*220, 300*300, etc. How to use different lenses is actually how to choose different focal lengths, which are mainly determined by several factors: the size of the object to be marked; the size of the range to be marked; the fineness of the processing and the overall matching of the equipment.

2The focal length has a certain relationship with the working distance. But the focal length is not equal to the working distance. When the object is relatively large and the marking range is increased, the required lens is relatively large. Usually like to scan and mark a large range. Warm reminder: If you blindly increase the scanning area, there will be many problems. That is to say, when the scanning area reaches a certain level, the diameter of the obtained light spot is large, the gathering is not fine enough, the light spot becomes larger, the distortion increases, the power density of the laser decreases rapidly, and the working distance increases, which will inevitably lead to the increase of laser energy. loss. Not conducive to precision machining.

3:In addition, when choosing the focal length, you should also consider the configuration of your equipment. If your equipment is a laser marking machine or a 10W fiber optic marking machine, it is recommended that the lens should not exceed 300*300, and the larger the laser lens is. , the consumption of the laser is also very large, the quality of the beam is not good, and the marking effect will decrease accordingly.
