Fiber End Cap

Fiber end cap is a high power device designed for processing the output end face of high power fiber laser and fiber amplifier, and a high power fiber passive device to realize the protection of fiber end face. By expanding the output beam, the optical power density of the output end is reduced, and the echo reflection of the end end is greatly reduced by using a special end Angle design.
