Protective Window / Protective Lens – 40×2 mm | Up to 15KW
The Protective Window / Protective Lens – 40×2 mm is a high-quality optical protection component designed for high-power laser cutting heads and laser cutting machines with power capacity of up to 15KW. It acts as a protective barrier for the internal optical components of the cutting head, helping reduce exposure to contaminants generated during laser cutting operations.
During high-power laser processing, metal spatter, smoke, dust, fumes, and cutting debris can enter the cutting head and contaminate the internal optics. The protective lens helps shield sensitive components from these contaminants while supporting efficient and reliable laser beam transmission.
