Protective Window / Protective Lens – 40×2.5 mm | Up to 15KW
The Protective Window / Protective Lens – 40×2.5 mm is a precision optical protection component designed for use with high-power laser cutting heads and laser cutting machines supporting power levels of up to 15KW. It provides an important protective barrier between the laser processing zone and the sensitive internal optical components of the cutting head.
During laser cutting operations, molten metal, spatter, smoke, dust, fumes, and other processing debris can contaminate the optical system. The protective lens helps shield the internal focusing optics from these contaminants, supporting clean optical transmission and reliable laser cutting performance.
