Laser marking machine no matter what kind, are made mostly the same components, the most important thing is laser, galvanometer mirror and field, and here we are saying is that the emergence of the lens on the spot out of the film mirror or dents and scratches and other damage should promptly after with the change, otherwise it will affect the marking effect, here to tell you about some of the situations with changing lenses need attention.

First, take the lenses must wear rubber gloves or finger, otherwise the hands of dirt and oil droplets will dirty lenses, the same will cause performance degradation, then the replacement is a meaningless action. Then do not use any tools to pick up lenses, and other sharp objects, such as tweezers, can also cause damage to the lens; the lens after removing the lens to put on paper, in order to avoid unnecessary damage, must not be arbitrary, on rough or hard surface, the lens is easily scratched, the last point to note is gold or copper surfaces clean and do not touch. Of course, if not necessary, or to ask a professional technician for replacement, if we must conduct its own replacement, be sure to pay attention to more attention to the situation.
