Optical equipment is more and more widely used, and many companies already have a large number of laser equipment, such as laser welding machines, laser marking machines, and laser cutting machines. In the process of using these equipment, the selection of some consumables is directly related to the use cost and product quality, such as: xenon lamp, krypton lamp, protective lens, especially the loss of protective lens. The main function of the laser protection lens is to prevent dust and splashes from damaging the focusing lens. However, if the lens is improperly selected, it will cause large laser loss, frequent damage to the protection lens, unstable product quality, and cause serious losses to the enterprise.

The principles of choosing laser protection lenses are as follows:

1) The external dimensions match, which is easy to understand;

2) Material, according to different laser powers, considering the cost of use, K9 and quartz can be selected. In the actual application process, professional manufacturers divide these two types of materials into multiple grades, and customers can choose the corresponding specifications according to actual needs;

3) Coating, laser anti-reflection coating, different coating technical parameters are adopted according to the use environment.

Laser lens wiping steps:

1. Hand wash, blow dry or wait to dry

2. Wear a finger cot

3. Gently remove the lens for inspection

4. First use an air ball or nitrogen to blow off the dust on the surface of the lens

5. Use a cotton ball dipped in mirror liquid to stick the residue away

6. Gently wipe with an appropriate amount of lens-wiping liquid with lens-wiping paper, and do not wipe in a rotating manner

7. Replace the lens cleaning paper and repeat step 6, laser protect the lens, do not reuse the same lens cleaning paper

8. Blow out the mirror with an air balloon

Laser lens maintenance taboos:

1. Do not touch the mirror with your hands

2. Do not blow air on the mirror surface or use air from an air compressor

3. Do not directly touch the surface of the hard object with the mirror surface

4. Do not wipe with non-lens paper (stick) or wipe hard on the lens

5. Do not press hard when disassembling and assembling the lens

Cleaning method of laser lens:

When cleaning the lenses, be very careful. Before cleaning the lenses, please see the following precautions:

1. Always wear finger cots or rubber gloves when handling the lenses, because dirt and oil droplets on your hands will stain the lenses and cause performance degradation.

2. Do not use any tools to pick up the lens, such as tweezers.

3. The lens should be placed on the lens paper to avoid damage.

4. Do not put the lens on rough or hard surfaces, the infrared lens is easily scratched.

5. Do not clean and touch the surface of pure gold or pure copper.
