Square Core Fibre

YOFC square core fibre is designed to meet special beam shaping requirements. Compared to a circular fibre profile, square-core fibre allows a more uniform treatment of the material-particularly in welding technology and heat treatment, as the beam moves laterally over the material's surface.

Applications
  • Coupled transmission required by special beam shapes
  • High-power laser transmission
  • Square diode laser and detector connected
  • Imaging and medicine
Characteristics
  • Perfect fibre 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
