We also use the field lens as the lens of the laser marking machine. This lens controls the marking range and is very useful. There are many issues to pay attention to during installation. Let's introduce them together below.
The correct installation process of the laser marking machine lens directly affects the engraving effect of the laser marking machine and the service life of the lens. If the installation method is incorrect, the lens will become dirty. Therefore, the previously mentioned operating procedures should be followed. If a large number of lenses need to be installed and removed, the fixture must be designed to perform the task. A special clamp reduces the number of contacts with the lens, reducing the risk of contamination or damage to the lens.
Additionally, if the laser marking machine lens is not installed correctly, the laser system will not work properly or even fail. All CO2 laser lenses must be installed in the same direction. Therefore, users must confirm the correct orientation of the lens. For example, a highly reflective output mirror surface should face the cavity, and a high transmittance surface should face the outside of the cavity. In reverse, the laser will not emit laser light or low energy laser light. The convex surface of the final focusing lens should face the cavity, and the second surface of the clear lens should be concave or flat, facing the working lens. If you flip it over, the focus becomes larger and the working distance changes. When cutting, the gap becomes larger and the cutting speed decreases.
The laser marking machine's reflector is the third commonly used lens, and its installation is also very important. Of course, it is easy to determine the reflective surface of a mirror. Apparently every lens manufacturer has a lens marking system where the coated side faces the laser. Typically for rearview and exit mirrors, the arrow points to the top reverse side. For lenses, arrows indicate concave or flat surfaces. Sometimes the labels on the lenses provide a reminder of what the markings mean.
