Light emitting device

A light emitting device comprising:

• a lens member having at least one lens surface;
• a submount having an upper face;
• and
• a plurality of light emitting elements arranged in a row on the upper face of the submount, the plurality of light emitting elements including:
• a first light emitting element configured to emit first light so as to pass through the at least one lens surface, the first light having an emission peak at a first wavelength from a first light emission point, and
• a second light emitting element configured to emit second light so as to pass through the at least one lens surface, the second light having an emission peak at a second wavelength from a second light emission point, the second wavelength being different from the first wavelength, and the second light emission point being located farther from the lens member than a first plane that is perpendicular to an optical axis of the at least one lens surface and that passes through the first light emission point;
• wherein:
• in a top view of the upper face of the submount as viewed from a normal direction thereof, inside a region surrounded by the first plane, a second plane that is perpendicular to the optical axis of the at least one lens surface and that passes through the second light emission point, a first line that is parallel to the optical axis of the at least one lens surface and that passes through the first light emission point, and a second line that is parallel to the optical axis of the at least one lens surface and that passes through the second light emission point, an outer edge of the upper face of the submount passes through a point that is farther from the lens member than the first plane and that is closer to the lens member than the second plane.
