Abstract: A fluorescent type of green light source of a semiconductor in a light source apparatus for an endoscope includes a blue excitation light source device and green emitting phosphor. The blue excitation light source device emits blue excitation light. The green emitting phosphor is excited by the blue excitation light, and emits green fluorescence. A dichroic filter in a dichroic mirror cuts off the blue excitation light from an emission spectrum of mixed light of the blue excitation light and green fluorescence from the fluorescent type of green light source. Thus, illumination light with the emission spectrum of a target can be stably supplied without influence of the blue excitation light to a light amount of blue light from a blue light source of a semiconductor.

Abstract: An in vivo endoscope illuminates tissue using multiple sources. Light from a short-range source exits a tubular wall of the endoscope through a first illumination region that overlaps an imaging region, and the light returns through the imaging region after reflection by tissue, to form an image in a camera. Light from a long-range source exits the tubular wall through a second illumination region that does not overlap the imaging region. The endoscope of some embodiments includes a mirror, and light from an emitter for the short-range source is split and reaches the first illumination region from both sides of an optical axis of the camera. Illuminating the first illumination region with split fractions of light results in greater uniformity of illumination, than illuminating directly with an un-split beam. The energy generated by each source is changed depending on distance of the tissue to be imaged.

Abstract: An endoscopic system having a light source that can operate in two modes is provided. The first mode provides a white light to an endoscope to transmit the light to a surgical site or other object, the reflection of which can be received by the endoscope and for the process. The second mode of the light source provides infrared excitation light and light in the blue and green wavelength spectra to an endoscope to transmit the light to an object such as a surgical site. The blue and green reflected light, as well as light from excitation markers, which is an infrared light at a different wavelength than the excitation infrared light, is received by the endoscope and further processed.
