clear aperture:>90%
Lens double sides with the high damage threshold >15J/cm2) coating to reduce reflection, transmittance can be increased to more than 99%.

laser protective glass is mainly used for blocking debris splashing in laser cutting, prevent splash from damaging the lens.
We choose optical crystal materials to make the laser protective glass, through cutting, grinding, polishing, coating and so on to complete the fine processes.
The laser protective glass can protect the damage of the focus lens, due to the AR coating on the surface is designed according to the wavelength 1064nm of the laser machine, so the Lens for laser cutting machine can extend the service life of the laser machine, reduces the use-cost greatly.
Lens double sides with the high damage threshold (>15J/cm2) coating to reduce reflection, transmittance can be increased to more than 99%.
