The principle and application of laser protection lenses

Laser protection lenses, are used to protect the focusing lens. Regular replacement of protection lenses can ensure the processing accuracy requirements.

Coating the lens with an anti-reflection film with a high damage threshold can effectively increase the transmittance of the lens, reduce the loss of damage energy, and improve the quality of processed products.

The working principle of laser protection lenses is mainly achieved through their special materials and structural design. The lenses use materials with high absorption rates to absorb the energy of laser beams, thereby reducing the damage of lasers to eye tissues or other sensitive parts. At the same time, the special design of the lenses can also reflect part of the laser beam away from sensitive areas. In addition, the lenses can also scatter the laser beam, disperse it in space, reduce the density of the beam, and further reduce the damage to sensitive parts.

Laser protection lenses are widely used in various laser processing equipment, such as laser cutting machines, laser welding machines, laser marking machines, laser engraving machines, etc. In these devices, laser protection lenses play an important role in protecting key components, improving processing accuracy and extending the service life of equipment.
