High Transmittance Transparent 60*3mm Laser Cutting Machine Lens

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
Total Absorption < 30PPM,Transmission > 99.9%
Diameter Tolerances: +.000”, -.005”

Thickness Tolerances: ±.010”
Parallelism: < 1 arc minutes

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.
