Get to know protective lens

Material:

The Protective lens material is crucial for its performance and lifespan. Common materials include quartz, borosilicate, K9,. These materials have properties such as high light transmittance, resistance to laser damage, and temperature resistance. It can shield against laser radiation and lens damage.

Use:

Protective lens are used in laser equipment such as cutting machines and welding machines. They prevent impurities such as debris from damaging the lenses and ensure smooth transmission of the laser beam.

Effect:

Protective lens protect the core component of laser equipment - the lens and are used to block debris and liquids. They also cut energy loss during laser transmission, boosting equipment efficiency.

Selection:

When choosing a protective lens, you should consider many aspects. The first step is to consider the laser device type, power, and wavelength and select the appropriate mirror material and coating based on this factor. Ensure adaptability to environmental conditions like temperature, humidity, and dust. Also, consider size and installation method compatibility with laser equipment. Opt for reputable brands and certified products for quality and performance assurance.

 

Correct Use of Protective Glasses

The protective lens is a wearing part and needs to be replaced in time after damage. When impurities or foreign matter adhere to the protective lens, it will cause damage to the protective lens. Thus, the protective lens needs to be cleaned regularly. The recommended cleaning cycle is one week.

Take out the protective lens

• Loosen the two locking nuts on the protective mirror assembly by hand and pull out the protective mirror drawer;
• Quickly seal the opening of the laser head after the lens is removed with a non-adhesive protective film;
• Place the protective mirror drawer (including protective lenses) in a clean environment for maintenance;
• Tear off the protective film on the laser head, insert the maintained protective lens cover (including the lens) flatly into the laser and lock it;
• If the direction of the protective lens cover is reversed, it will not be inserted;
• Use your hands to tighten the two locking nuts on the protective lens assembly with appropriate strength.

Note: Do not use iron tools for the operation, otherwise the parts will be damaged!

 

 

 

 

 

 

 

 

Install protective lens

• Remove protective lenses

After slightly removing the fixing ring 1, remove the protective lens 2;

Put 2 protective lens covers into a clean container, and the mirror surface cannot come into contact with non-gaseous substances.

• Clean and Protect Lens

Use a dust-free cleaning rod dipped in isopropyl alcohol solvent to clean and protect the lens. Then use the Pihu to absorb clean air and blow off the attached particles and other foreign matter;

Repeat several times until the lens is clean;

If the protective lens cannot be cleaned or is damaged, a new lens must be replaced now.

• Check the sealing ring

Check whether the sealing ring is deformed or notched, which may cause air leakage. The sealing ring must not be dropped to the ground or in a dirty, dusty, or rough environment.

• Install protective lens

Carefully put the clean 2 protective lens into the 4 support;
Put in the fixing ring 1, and pay attention to check whether the sealing ring 3 is under the protective lens.

Clean and Protect Lens

• Cleaning tools:

Dust-proof gloves, polyester fiber cotton swabs, ethanol, and rubber air blowers.

• Cleaning method:

Wear finger cots on the thumb and index finger of the left hand;
Spray ethanol onto the polyester fiber swab;
Gently hold the side edge of the lens with the thumb and index finger of your left hand. Be careful not to touch the surface of the lens with the finger cot;
Place the lens facing your eyes, hold the polyester fiber swab in your right hand, and blow the lens surface from bottom to top. Both front and back sides must be cleaned, and after cleaning, confirm again that there is no residue.

 

The protective mirror is a very important part of the laser machine. Correct use can extend the life of the machine and ensure the production efficiency of the equipment. Thus, please strictly follow the correct operating procedures to avoid unnecessary damage to the machine.
