Abstract
An endoscope tip having an objective for imaging a field of view, and further having an illumination device for illuminating the field of view. The objective has an angle of view greater than 180°, the illumination device is arranged around the objective, and the illumination device includes a transparent cap from which the illumination light is emitted into the field of view. The illumination device further includes one or more light emitting devices that emit emission light, and for one of the light emitting devices, a centroid of an angular distribution of the emission light is located in a direction tilted away from the optical axis, or a reflective surface reflects at least the emission light in a direction further away from the direction of the optical axis than a direction in which the emission light is incident on the reflective surface.
