Abstract
A light-source device including a light-emitting element to emit light, a light-receiving system, an acquisition unit, a setting unit, and an adjuster. The light-receiving system receives the light emitted from the light emitting element. The acquisition unit acquires a wavelength of the light emitted from the light emitting element. The setting unit sets a target value of an amount of the light received by the light-receiving system based on the wavelength acquired by the acquisition unit. The adjuster adjusts an amount of the light emitted from the light emitting element such that the amount of the light reaches the target value of the light that is set with the setting unit.
