D20 Series Fiber Laser Protective Lens Windows 20*2/20*4/21.5*2/22.35*4/24.9*1.5 1064nm Laser Head Cutting Welding Glass

Product Features

The D20 Series fiber laser protective lens windows, made of fused silica, have a plano-convex structure and are suitable for laser cutting and welding applications.
With a transmission rate of 99.5% and a wavelength of 1064nm, they can effectively protect the laser head and ensure high-quality laser processing.
They have a diameter tolerance of ±0.01mm and a thickness tolerance of ±0.01mm, ensuring precise optical performance.
The clear aperture is ≥90%, allowing for efficient laser transmission and reducing energy loss during the laser process.
These lenses are designed for optical use and can work with lasers with a power range of 0-6000w, meeting the needs of different laser applications.
