Square Core Fiber
Everfoton's Square Core Fiber with special optical spot shaping requirements is developed using the independent patented manufacturing platform.Compared with circular core fibers,the square-core fiber produces output beams that are close to square-shaped. This shape allows for a more uniform treat-ment of output spot energy, making it particularly suitable for high-efficiency welding and heat treatment.
Perfect fiber geometries and low transmission loss
Standard symmetrical square shape with adjustable square core corner radius
Homogeneous beam output of the square core
Customized shape and size requirements
