Details Introduction
Square Core Fibre with special optical spot shaping requirements is developed using the advantages of PCVD preparation of fluorine-doped rods and combining cold processing and polishing treatment. Compared with circular core fibres, the square-core fibre produces output beams that are close to square-shaped. This shape allows for a more uniform treatment of output spot energy, making it particularly suitable for high-efficiency welding and heat treatment.
Applications
• Coupled transmission required by special beam shapes
• High-power laser beam shaping
• Square diode laser and detector connection
• 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
