What kind of safety glasses do we need when using a CO2 laser?

When using CO2 lasers, specific safety glasses are required to protect the eyes from laser damage. The optical density (OD) level is considered. The following are the requirements for safety glasses suitable for CO2 lasers:

I. Protective wavelength

The wavelength of CO2 lasers is usually around 10.6 microns. Safety glasses should be able to effectively block laser radiation of this wavelength. Choose glasses with high optical density (OD) values for the wavelength of CO2 lasers to ensure adequate protection. Generally speaking, the higher the OD value, the better the protection. The optical density (OD) level is a key factor to consider when choosing laser safety glasses, and is usually marked directly on the glasses. For CO2 lasers, it is recommended to choose glasses with an OD level higher than 5 to provide adequate protection.

2. Material and quality

① Lens material:

Usually high-quality optical materials such as polycarbonate are used. This material has good impact resistance and optical properties, and can withstand the heat and pressure that may be generated by laser irradiation.

The lenses should be specially treated to improve their wear resistance and scratch resistance to ensure that the protective effect is not reduced due to wear during use.

② Frame design:

The frame should be strong and durable, able to stably fix the lens, and fit tightly to the face to prevent the laser from entering the eyes from the side.

3. Certification and standards

Choose safety glasses that meet international standards, such as products certified by the American National Standards Institute (ANSI), European Standards (EN), etc. These standards ensure the quality and protective performance of safety glasses.

4. Other considerations

① Visible light transmittance: Under the premise of ensuring laser protection, choose glasses with high visible light transmittance so that you can clearly see the surrounding environment during operation.

② Cleaning and maintenance: Clean safety glasses regularly, use special cleaning fluid and soft cloth to wipe the lenses, and avoid using rough materials or chemical solvents to avoid damaging the lenses.

③ Storage: Store safety glasses in a dry, clean place, avoid direct sunlight and high temperature environment to extend their service life.

In short, it is crucial to choose the right safety glasses when using carbon dioxide lasers. Be sure to choose high-quality safety glasses that meet the standards based on factors such as the laser's wavelength, power, and operating environment, and wear and maintain them correctly to ensure eye safety.
