Abstract
A light emitting device includes a base, a lid portion, a plurality of semiconductor laser elements, and a collimate lens. The lid portion is fixed to the base to define a hermetically sealed space by the lid portion and the base. The semiconductor laser elements are provided in the hermetically sealed space. The collimate lens has a non-lens portion fixed to the lid portion, and a plurality of lens portions connected and aligned along one direction and surrounded by the non-lens portion when viewed from a light extracting surface side of the collimate lens.
