Fiber End Cap
A fiber end cap is a precision optical element whose core function is to protect, process, and optimize the laser output from the fiber end face. It is usually made of high-quality optical materials (such as quartz, sapphire, or various optical glasses). One end is fused or bonded to the fiber through a precise process, while the other end undergoes precise optical machining.
