Description
The D38.1×1.6-PW-6KW Protective Window Lens is an essential consumable for high-power fiber laser cutting systems. Measuring 38.1 mm in diameter and 1.6 mm in thickness, it acts as a protective barrier between the laser beam and the internal optical components.
Constructed from high-quality fused silica (quartz) and coated with a precision anti-reflective (AR) coating, this lens delivers outstanding laser transmission while resisting scratches, heat, and contamination. It helps extend the life of expensive collimation and focusing lenses by preventing damage caused by metal spatter, dust, oil, and smoke generated during laser cutting.
Suitable for 6KW laser cutting machines, this protective window ensures stable beam quality, consistent cutting accuracy, and reduced machine maintenance costs. It is ideal for cutting stainless steel, carbon steel, aluminum, brass, copper, and other metals
