Protective Lens 37 × 3.5 mm – 15 kW
The Protective Lens 37 × 3.5 mm – 15 kW is a high-quality optical component designed for compatible 15 kW high-power fiber laser cutting machines. It functions as a protective window inside the laser cutting head, helping shield the internal focusing lens and other sensitive optical components from dust, smoke, sparks, metal particles, and cutting debris generated during laser operations.
Manufactured to precise dimensions, this protective lens features a 37 mm diameter and 3.5 mm thickness, providing a reliable fit for compatible laser cutting heads and optical assemblies. Its excellent optical clarity and laser transmission help maintain stable beam performance and support consistent cutting quality during high-power laser processing.
A clean and properly maintained protective lens is essential for efficient laser operation. By acting as a barrier between the cutting zone and internal optics, this lens helps reduce contamination and can minimize the risk of optical damage caused by particles and debris. Regular inspection and replacement can also help maintain reliable machine performance and reduce unnecessary downtime.
