3V TECHNOLOGY is a processing factory of integrated R&D, manufacturing and direct-exporting,which has a strong production base and sales network. we can customize protective lenses of different sizes and wavelengths according to customer requirements.

Laser protective lens is mainly used to prevent debris splashing during cutting and prevent splashing from damaging the lens. Both sides are AR coated with high LIDT (> 15j/cm2) to reduce reflection. At present, it is widely used in laser cutting, laser welding, laser marking and other applications.
