Fiber protective window, shaped as Plano-plano window, coated AR/AR @ 1030-1090nm at both sides, material adopted JGS1 or Fused Silica(FS). The protective window is used at laser cutting head to protect the focusing lens in case of damage. We can provide any wavelength coating according to customer demand. For other wavelengths, diameter, thickness and coating, we can also produce as customized requirements.
