High Power Laser Protection Lens Window Sapphire Material For Laser Cutting Machine
D32 4mm Laser Protection Lens 1064nm Sapphire Optical Windows
Protect windows for your fiber laser cutting head are relatively inexpensive and ensure that your expensive lens package remains protected inside the laser head. In practice, we often see that people try to save a few dollars on protective windows and then have to spend thousands of dollars on expensive lens packages.
These ultra clean windows are made of Fused Silica quartz and are highly transparent to the infrared laser light around 1080 nm wavelength. They also offer good resistance to high auxiliary gas pressures, protecting the collimator lens and focus lens.
