    • A device for introducing illuminating light that is emitted from a light source to an illuminating light guide fiber bundle associated with an endoscope. The device has an incident end face of the light guide fiber bundle that is disposed at a position where the light from the light source is converged, and a lens which is disposed in close proximity to the incident end face of the light guide fiber bundle. That lens has a convex surface which faces the light source and a concave surface which faces the light guide fiber bundle.Accordingly, the illuminating light is refracted by the concave surface of the lens so as to enter the light guide fiber bundle at a small angle to the optical axis. Thus, the illuminating light is transmitted through the light guide fiber bundle with a considerably small number of times of reflection.
    • 一种用于将从光源发射的照明光引入到与内窥镜相关联的照明光导纤维束的装置。 该装置具有设置在来自光源的光会聚的位置处的导光纤维束的入射端面和与导光纤维束的入射端面紧密配置的透镜。 该透镜具有面向光源的凸表面和面向导光纤维束的凹面。 因此,照明光被透镜的凹面折射,以便以与光轴成小角度的方式进入导光纤维束。 因此,照射光以相当少的反射次数透过导光纤维束。
