High Transmittance Imported Quartz JGS1 laser protective lenses
1064nmAR coated φ60*3mm 99.9% optical window film 3000W
Laser protective lens:
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. 0.2 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

Fearture:
1. 4-5 times harder than ordinary float glass, stronger resistance
to thermal breakage than annealed or heat strengthened glass.
2. once breakage occurs, the glass disintegrates into small cubical
fagements, which are relatively harmless to human body.
3. Suitable for use a safety glass as defined by consumer product
safety association.
