Light source device and endoscope system

Abstract

There are provided a light source device, which is more compact and inexpensive than a known light source device, and an endoscope system having a compact and inexpensive light source device. In a light source device, a light source unit includes a first light source that emits blue light, a second light source that emits broadband green light including not only a green component but also a red component, and an optical filter that adjusts the amount of broadband green light for each wavelength. The optical filter has a characteristic in which the reflectance of the green component is smaller than the reflectance of the red component in the case of reflecting the broadband green light or a characteristic in which the transmittance of the green component is smaller than the transmittance of the red component in the case of transmitting the broadband green light.
