TOP® Multicore FiberTOP® Multicore Fiber

TOP® multicore fibers open new capabilities for laser power delivery: by using different cores, or several cores at once, power density and beam shape can be precisely controlled. TOPRAYS offers customizable multicore fibers to meet your specific needs.
Advantages
Supports kilowatt-level power
Non-circular core shapes possible
Precise control of power density
Higher precision
Step-index profile
Special jackets available for high-temperature, high-vacuum and highly corrosive chemical environments
