Abstract

PURPOSE:To facilitate the adjustment of a coupling element for optical branching by adjusting and assembling fibers and lens elements such that the output lights from the lens elements are directed normal to the reference surface at the beam splitter side of the lens elements and are produced as parallel fluxes of light.
