1. Focusing effect: The focusing lens is a key part of the laser cutting head, which uses the optical principle to focus the laser beam into a very small high-energy spot, so as to achieve fast and deep cutting of the material. Good focusing ability is directly related to cutting speed, precision and edge quality.

2. Protection mechanism: the protection lens is located at the front end of the cutting head, designed to block the slag, dust and other impurities generated during the cutting process, protect the more fine and expensive focusing lens and internal optical system from damage, and extend the service life of the equipment.

3. Improve performance: high-quality lenses can significantly improve the performance of the laser cutting machine, including enhancing the cutting speed, optimizing the smoothness of the cutting surface, and reducing the auxiliary gas consumption, thereby improving the overall processing efficiency and economic benefits.

4. Vulnerability and maintenance: the lens is a wearing part, need regular inspection and cleaning and timely replacement. Oil, scratches or damage will affect the laser transmission efficiency and reduce the cutting quality. Proper cleaning and maintenance methods are crucial to keeping your lenses in top condition.

5. Selection and matching: Select the right lens to consider the wavelength of the laser, cutting material type and thickness and other factors. Different materials and designs of lenses are suitable for different processing needs, and the right choice can maximize the efficiency of the equipment.
