Document Type and Number:
Japanese Patent JP6681454
Kind Code:
B2
Abstract:
To provide a light source device for an endoscope, an endoscope system, and a position adjusting method capable of reducing a change in a hue of a display image in each of endoscopic diagnoses when using a plurality of monochrome semiconductor light sources emitting a light of a plurality of colors respectively.SOLUTION: A collimator lens 75 that transmits a blue color light BL from a blue semiconductor light source 35 and a collimator lens 77 that transmits a red color light RL from a red semiconductor light source 37 are provided with adjusting mechanisms 81 and 82 respectively. The adjusting mechanisms 81 and 82 cause a focal position BFP of the blue color light BL and a focal position RFP of the red color light RL to coincide with a focal position GFP of a green color light GL by moving the collimator lenses 75 and 77 in an optical axis OA direction. The adjusting mechanisms 81 and 82 include a guide mechanism for guiding the movement of the collimator lenses 75 and 77 in the optical axis OA direction, a moving mechanism for moving the collimator lenses 75 and 77 in the optical axis OA direction, and a fixing mechanism for fixing the positions of the collimator lenses 75 and 77.SELECTED DRAWING: Figure 15
