Laser Focusing Lenses: Cleaning and Maintenance Methods

Laser focus lenses include a variety of optical lens types, including PCX lenses, aspherical lenses, cylindrical lenses or laser generator lenses. In the process of cutting machine, the focusing lens will be contaminated by some pollution, such as water pollution or dust pollution, etc. Cleaning the lens is not a simple task. This article explains the correct way to clean the laser lens.

 

Pillow Packaging Machine Manufacturers include a variety of optical lens types, including PCX lenses, aspherical lenses, cylindrical lenses or laser generator lenses. In the process of cutting machine, the focusing lens will be contaminated by some pollution, such as water pollution or dust pollution, etc. Cleaning the lens is not a simple task. This article explains the correct way to clean the laser lens in the laser cutting machine.

 

 

Preventive measures

During the installation and cleaning of the lens, any little sticky matter, even nail marks or grease, can damage the service life. Therefore, the following precautions must be applied.
1. Never mount lenses with bare fingers. You should bring finger covers or rubber gloves.
2. Do not use sharp instruments to avoid scratching the surface of the lenses.
3, do not touch the film layer when taking the lens, but hold the edge of the lens.
4, laser cutting machine lenses should be placed in a dry, neat place.
5, the user should avoid talking over the lens, so that food, drinks and other contaminants away from the work environment.

Maintenance of the lens

Although the focusing lens is a perishable part, but in order to improve its utilization and reduce production costs, people can regularly clean and protect the lens to achieve reuse. The following are some of the methods shared by Manufacturer BOFA.

 

Magnification

Most contaminants and surface defects are small in size and we often need magnification equipment when examining lenses. In addition to magnifying glasses and microscopes, sometimes we need to shine a brighter light to enhance the intensity of the specular reflection of surface contaminants and defects, so that contaminants and defects can be more easily detected.

 

ZnSe

ZnSe (zincated arsenic) material is brittle and afraid of falling; when disassembling and assembling, one should pay attention to: not to use too much force and not to collide with hard objects. It is afraid of pollution, moisture, oiliness and scratching; therefore, it requires dry and de-oiled air to be provided during the work.
You can operate with gloves and their special sets, for smaller lenses, it will be more convenient to use optical tweezers or vacuum tweezers.

 

 

Wipe

When cleaning a focusing mirror, always use clean wiping paper and an optical grade solvent to prevent damage by other contaminants. Wiping paper must be moistened with the appropriate solvent, never used dry. For softness reasons, the available wipes are cotton Webril wipes or applicators such as cotton balls, lens paper, and cotton swabs.

 

Focusing lens is supposed to be consumable, if after cleaning it many times, you find that it still does not reach the cleanliness, it needs to be replaced to ensure the processing efficiency of the laser cutting machine, so as not to delay production and bring losses to the enterprise.
