Optical lenses in laser systems are consumables. To maximize lifespan and reduce service costs, they must be cleaned strictly according to this specification. During the replacement process, the placement, inspection, and installation of optical lenses should be handled with care to prevent damage and contamination. After installing a new lens, regular cleaning is required. Of course, cleaning the lenses cannot be done like cleaning glasses; you need to be attentive.

During laser cutting materials, a large amount of gas and splatter is released from the working surface, which can damage the lens. When contaminants fall onto the lens surface, they absorb energy from the laser beam, resulting in a thermal lens effect. If the lens has not yet formed thermal stress, the operator can remove and clean it. During the lens installation and cleaning process, any trace of viscosity, even a drop of nail polish, can increase the lens' absorption rate and reduce its lifespan. As an example of daily operations with Rayyu laser lenses, the following precautions should be taken:

Never wear lenses with exposed fingertips. Use finger covers or rubber gloves.

Do not use sharp instruments to avoid scratching the lens surface.

When holding the lens, do not touch the film, but grip the edge of the lens.

4. Lenses should be tested and cleaned in a dry and clean area. A good workbench surface should have several layers of cleaning tissues and a few sheets of lens cleaning wipes.

Users should avoid speaking above the camera and keep food, beverages, and other potential contaminants away from the work environment.

During the lens cleaning process, it is recommended to use methods with relatively lower risks. For this purpose, the following steps have been established and should be adopted by the user.

Blow off debris from the original parts with a balloon, particularly for lenses with fine particles and fibers on the surface. However, do not use compressed air on the production line, as it contains oil mist and water droplets that can worsen the lens contamination.

2. Gently clean the lenses with pure acetone, which is nearly anhydrous, thus reducing the likelihood of crystalline contamination.

Cotton balls soaked in acetone should clean the lens under light and perform circular movements. Once the cotton swab becomes dirty, it should be replaced. The cleaning should be completed simultaneously to avoid creating wave tendons.
