Abstract

A light-emitting device (1; 2; 3; 4) includes a substrate (10); a lens array (20) having a plurality of lens sections (22) in a matrix pattern; and a plurality of semiconductor laser elements (30) disposed on the substrate. Each of the semiconductor laser elements emits a respective laser beam, each laser beam having a beam shape with a greater width in a column direction (Y) than in a row direction (X) on a light incident surface of each respective lens section. The lens sections have an inter-vertex distance (PX) in the row direction that is smaller than both (i) a maximum outer diameter (E) of each of the lens sections, and (ii) an inter-vertex distance (PY) in the column direction. A curvature (RX) of the lens sections in the row direction is the same as a curvature (RY) of the lens sections in the column direction.
