What is Laser Protective Window?

The Laser Protective Window is a Consumable Used in Laser Welding Guns or Laser Cutting Heads to Protect the Collimating and Focusing Lenses in the Laser Head. When We Use Laser Cutting Machines and Laser Welding Machines to Weld and Cut There is Dust, Metal Slag, and Other Debris Bouncing into the Laser Head During the Welding and Cutting Process. So We Need to Add a Laser Protective Window to Protect the Focusing Lens from Burning.
The Laser Protective Window Substrate is Made of a Quartz Sheet, Coated on Both Sides with a Transmission-enhancing Film. Generally, the Laser Transmittance is More Than 95%, Which Does Not Affect the Laser Power and Performance.
