  • Publication number: 20210285609
    Abstract: A light source device includes: light sources configured to emit kinds of light having wavelength band different from one another; dichroic mirrors that are respectively arranged on a first optical path, the dichroic mirrors having light transmission characteristics different from one another, each dichroic mirror being configured to reflect or pass light emitted from any one of the light sources; light sensors that are respectively positioned on second optical paths, each second optical path being a different optical path from the first optical path and being an optical path propagating light reflected on or passed through the dichroic mirror, each light sensor being configured to detect a light amount of light that propagates through the second optical path; and a controller configured to control a light amount ratio of the kinds of light based on the light amount respectively detected by the light sensors.

  • Patent number: 10779716
    Abstract: A light source system includes a normal light source apparatus provided with a light source controller and a light source apparatus for specific light provided with a specific light controller. In a state where communication is enabled, the light source controller adjusts an emission intensity of the normal light, generates a light amount control signal that makes the normal light and the specific light have a predetermined light amount ratio, and sends the light amount control signal to the light source apparatus for specific light. The specific light controller adjusts an emission intensity of the specific light based on the received light amount control signal.
