Protective Window/Lens 37×7 mm for Laser Cutting Head – Up to 10KW, 15KW & 20KW
The Protective Window/Lens 37×7 mm is a high-quality optical protection component designed for compatible fiber laser cutting heads and laser cutting machines with power capacities up to 10KW, 15KW, and 20KW. It provides an essential protective barrier between the cutting zone and the sensitive internal optical components of the laser cutting head.
During laser cutting operations, the cutting area produces smoke, dust, sparks, molten metal, metal particles, and other debris. The protective window helps shield the internal optics from these contaminants, reducing the risk of optical contamination and supporting reliable laser cutting performance.
