Optical module for a semiconductor light-emitting device

摘要

An optical module includes a semiconductor light-emitting device and a lens structure, which are held by a housing while being optically aligned with each other. A ferrule of an optical plug to which the optical module is to be coupled is fittingly received by the housing. The lens structure includes a pair of cylindrical lens portions, which are oriented orthogonal to each other and located at positions spaced from each other in the optical axis direction.
