Focusing collimating lens assembly in laser cutting head usually includes two main lenses: collimating lens and focusing lens. Collimator lens: used to recombine the scattered laser beam into a parallel beam after the laser beam is transmitted through optical fiber. Focusing lens: focuses the collimated parallel light beam on a very small point, thus producing high-density energy points when cutting materials. If the lens is damaged or contaminated, it may lead to a decrease in laser cutting efficiency or a bad cutting effect. Therefore, it is necessary to pay special attention to the cleaning and maintenance of lenses during use.
