End Cap with Glass Sleeve
A fiber end cap is formed by splicing a short silica rod or GRIN fiber to a fiber end face. There are two main types: a fused-silica rod spliced to a fiber to reduce optical energy density at the transmission interface of a high-power laser fiber, and a self-focusing lens end cap formed by splicing GRIN fiber to ordinary single-mode fiber for miniature imaging requirements.
