Abstract: A light source device includes light sources, a light output unit, optical filters, temperature sensors detecting current temperatures of the sources, light quantity sensors detecting current light quantities of light beams before traveling through the filters, a storage, and a processor. The storage stores first correlation information between the temperatures of the sources and spectral information and second correlation information between the spectral information and light quantity of light at the unit. The processor is configured to calculate a variation in the spectral information based on each current temperature and the first information, calculate a variation in the light quantity of the light at the unit caused by a change in the spectral information based on the variation in the spectral information and the second information, and calculate a light-quantity correction amount for each of the sources based on the variation in the light quantity and the current light quantity.

Abstract: An endoscope of the present invention includes a first positive lens configured to concentrate light emitted from a light source onto an internal focus point and to emit the concentrated light to irradiate an object. The focus point is located on an incidence side from an intermediate point on an optical axis of the first positive lens.
