1.The protective window is used at laser cutting head to protect the focusing lens in case of damage.
2.Fiber protective window , shaped as Plano-plano window, coated AR/AR @ 1030-1090nm at both sides.
3.Material adopted high-quality JGS1 or Fused Silica(FS). After polishing, coating both sides and other fine processing, making it high transmittance, high temperature and humidity resistance, strong resistance to laser.
4. 0.5 mm*45° protective chamfering, follow the requirements of humanized design.
5.We can provide any wavelength coating according to customer demand. For other wavelengths, diameter, thickness and coating, we can also produce as customized requirements.
Standard, high efficiency, low loss anti-reflectance
Thin film coating applied to both sides
Total Absorption < 30PPM,Transmission > 99.9%
