Maintenance And Upkeep Of Laser Protective Lenses

The cleanliness of laser protective lenses has a significant impact on the processing performance and quality of laser equipment. The following are specific maintenance measures:

Cleaning steps
Preparation: Wash hands thoroughly, blow dry or wait to air dry, wear finger cots or rubber gloves as dirt and oil droplets on hands can dirty the lens and cause performance degradation. Choose a place with less dust to clean the lenses.
Removal and inspection: Gently remove the lens and inspect it. A relatively bright beam of light can also be used to illuminate the optical surface, enhancing the specular reflection intensity of surface pollutants and defects, making it easier to detect pollutants and defects.
Blow off dust: First, use an air balloon or nitrogen to remove dust from the surface of the lens, avoiding using an air compressor to blow air as this may cause damage to the lens.
Stick off residue: Use a cotton ball dipped in lens cleaning solution to stick off the residue.

Wipe the lens
Drop an appropriate amount of lens cleaner liquid onto lens cleaning paper and gently wipe it. Do not use the rotating method. To replace the lens cleaning paper, repeat this step and do not reuse the same lens cleaning paper.
When wiping, take a flat lens wiping paper and cut it in half. Drop a small amount of 99.5% pure alcohol on the lower surface of the lens wiping paper. Due to the filtering effect of the lens wiping paper, use the lower surface of the lens wiping paper to contact the lens for wiping. When picking up the lens with fingertips for wiping, be careful not to raise your fingertips above the surface of the lens. Place the wiping paper with alcohol on top of the lens, pull it back and forth slightly to fully adhere to the lens and loosen any contaminants on the lens. Then gently pull it in one direction.
Blow the mirror clean: Use an empty balloon to blow the mirror clean.

Maintain taboos
Avoid touching the mirror: Do not touch the mirror with your hands, as dirt and grease on your hands can dirty the lens and cause performance degradation. Do not use tweezers or any other tools to pick up the lens. When taking out the lens, it should be taken from the side of the lens.
Proper use of blowing tools: Do not use an air compressor to blow air onto the mirror surface to prevent damage to the lens.
Prevent contact with hard objects: Do not let the mirror directly contact the surface of hard objects. When disassembling and installing the lens, do not apply too much force and do not collide with hard objects to avoid damage to the lens.
Use appropriate cleaning tools: Do not use non lens cleaning paper (stick) to wipe or forcefully wipe the lens. Instead, use clean wiping paper and optical grade solvents. The wiping paper must be moistened with a suitable solvent and cannot be used dry. The available wiping paper includes pure cotton Webril wiping paper, cotton balls, lens paper, cotton swabs, and other applicators.
Avoid incorrect operation: Do not press hard when disassembling the lens; When installing or replacing lenses, do not use too much pressure, otherwise it will cause deformation of the lenses, which will affect the quality of the light beam.

Storage precautions
Place in the appropriate position: The lens should be placed on lens paper to avoid damage. Do not place the lens on rough or hard surfaces, as it may easily scratch the lens. When the lens is damaged, it should be promptly contacted with the after-sales service department for repair. Try not to use damaged lenses, otherwise it will accelerate the damage of lenses that could have been repaired.
Ensure suitable environment: The surface of the lens has an anti reflective film, which is afraid of pollution, moisture, oil, and scratches. Therefore, it is required to provide dry and degreased air during work.

Regular Inspection
Regularly (at least once a month) inspect the surface contamination of the lenses based on the workshop environment, and clean the optical lenses in a timely manner to ensure their service life. Generally, it is necessary to check the condition of laser protective lenses before use and before and after cleaning.
