Abstract: A semiconductor light emitter includes a substrate, a semiconductor multilayer structure including a light emission unit that emits light in an oblique direction with respect to the substrate, a base on which the substrate is disposed, a holding member that holds the substrate at an angle set in advance with respect to the base, a temperature control unit disposed parallel to the substrate to adjust a temperature of the substrate, and a shaping optical system held against the substrate to shape a luminous flux emitted from the semiconductor multilayer structure.
