AT's Fiber Laser Protective Windows & Lenses

AT Protective Windows and Lenses are designed for workshops that want reliable fiber laser optics without paying premium brand prices. This collection covers popular AT sizes such as 24.9x1.5mm & 27.9x4.1mm (4KW-6KW), 30x5mm (6KW) and 37x7mm (12KW) providing both top and bottom protective windows and curved lenses for high‑power cutting heads. Built to solid Chinese industrial standards, these parts deliver stable performance for everyday production while keeping your operating costs under tight control.

Each AT protective window and lens is manufactured from coated optical glass to maintain good laser transmission and protect focus lenses from dust, smoke, and metal splash. The precise diameters and thicknesses are matched to common fiber laser heads, making replacement fast and straightforward on most Chinese and OEM machines. For fabrication shops in Lahore, Karachi, Faisalabad, and across Pakistan, AT optics from Abdul Traders offer a practical balance of durability, cut quality, and price—often beating the market on cost while still delivering dependable results.
