Fiber Laser Air Spaced Focusing Lens

Fiber Laser Air Spaced Focusing Lens

Eternal Optics manufactures high-precision Fiber Laser Air Spaced Focusing Lenses designed for high-power fiber laser cutting, welding, and industrial processing systems. Optimized for 1030–1080 nm wavelengths, including the widely used 1064 nm and 1070 nm fiber lasers, our air-spaced focusing lenses provide excellent beam focusing performance, high transmission efficiency, and superior thermal stability.

Unlike cemented lens designs, Air Spaced Focusing Lenses use precision mechanical spacing between optical elements, offering improved thermal performance, higher power handling capability, and enhanced reliability for demanding high-power laser applications. These lenses are ideal for systems requiring stable focus quality and long operating life under continuous laser exposure.

Our Fiber Laser Air Spaced Focus Lenses are manufactured using premium optical materials with advanced anti-reflective (AR) coatings optimized for near-infrared fiber laser wavelengths. They provide low optical absorption, high laser damage resistance, and excellent beam quality for precise laser processing.
