Photonwares’s optical fiber end cap can much reduce the power density at the interface between fiber and air offering much higher transmitted power from fiber cores in a miniature format. Based on Photonwares’s beam shaping technology, a high quality end cap is uniquely formed directly at the fiber tip that transmitting uniformly beam spot.

Besides, a mode stripping technique is incorporated into the fiber end cap to clean up the forward and backward cladding light.
