The Raytool Protective Lens (genuine Raytools protective window) is a precision fused-silica optic that shields the focusing and collimation lenses inside a fiber laser cutting head from spatter, smoke, fumes and thermal damage. As a low-cost sacrificial consumable, it keeps beam quality stable, protects high-value internal optics, and ensures clean, consistent cut edges in daily industrial production.
Our Raytool protective lenses are made from high-grade fused silica (quartz) and anti-reflective (AR) coated on both faces for 1064-1080 nm fiber laser wavelengths, delivering over 99% transmittance for maximum power throughput. They are available in all standard Raytools sizes - including 24.9x1.5 mm and 27.9x4.1 mm collimation/focusing windows, plus 30x5 mm and 37x7 mm for higher-power heads - and fit BM109, BM111, BM114S, BT210S, BT240S and BT240S-RC cutting heads with drawer-type lens holders for fast replacement. Trusted by sheet metal fabrication units, automotive manufacturers and laser job-work shops across India, every lens is dispatched from our Ahmedabad warehouse with GST invoice and pan-India delivery.
Precision fused-silica protective windows with dual-side AR coating for 1064 nm, high transmittance and a high laser-damage threshold. Engineered to drop into standard Raytools focusing and collimation lens holders.
Protects expensive focus and collimation optics, maintains cut quality, reduces downtime and lowers maintenance cost. The ideal routine consumable for production-grade fiber laser cutting.
