Laser windows and laser dust-proof lenses are other names for laser protection lenses. They are primarily used to cover the focusing lens and prevent sputtering splashes from damaging the lens. To ensure the accuracy of processing, the protective lens must be replaced on a regular basis. The lens’s anti-reflection coating, which has a high damage threshold (>15Jcm2), can effectively boost the lens’ transmittance while minimizing energy waste and enhancing the quality of processed goods.

It’s commonly utilized in laser processing equipment such laser cutting machines, laser welding machines, laser marking machines, and laser engraving machines, among others.

Good Features

  • Made of imported quartz with a double-sided coating that increases laser penetration while decreasing power consumption.
  • Not easily cracked and long-lasting
  • High welding efficiency and long-term stability
  • Heat-resistant having excellent optical, thermological, and mechanical properties.


Laser welding and cutting are becoming increasingly popular in industrial settings due to their efficiency and accuracy. However, these processes are potentially dangerous if appropriate safety measures are not taken. One of the most important safety measures that should be taken is to wear proper protective lenses, which can protect your eyes from the intense light emitted by the laser. The lens offers a variety of benefits including increased safety, improved accuracy, and increased efficiency.

    I purchased it and had it shipped to the workshop for installation on the machine. After the machine is mounted, the thickness of the lens is consistent, clean, and transparent, and the welding effect is excellent.
