Problems solved by technology

Therefore, the optical fiber surrounding the observation optical system may cause the outer diameter of the insertion part to become thicker.
In addition, since the tip of the optical fiber is brought into contact with the prevention part, part of the illumination light irradiated from the tip of the fiber directly enters the tip without passing through the lens system, which may adversely affect the optical performance.

Abstract

This endoscope 10 comprises: a first fiber 61 of a light guide fiber 60, the first fiber 61 having a tip part on which a first flat surface 61f for emitting illumination light is provided, the first flat surface 61f being formed inclined at an angle of less than 90 degrees with respect to a longitudinal axis 61a; a pipe 70 which has a through hole 71 to which a tip portion 61p of the first fiber 61 is secured and which has a tip surface 73 that includes a first surface 73a capable of being flush with the first flat surface 61f and a second surface 73b which is a flat surface orthogonal to the central axis 71a of the through hole 71; and a tip component 30 which has a blind hole 34 into which a tip end of the pipe 70 is disposed, wherein the bottom side of the blind hole 34 is provided with an abutting surface 38f2 to which at least a part of the second surface 73b of the pipe 70 abuts and a recess 37 which is positioned further to the tip side than the abutting surface 38f2 and forms a portion of an illuminating lens system for obtaining a predetermined light distribution.

Description

technical field [0001] The present invention relates to an endoscope configured such that an end portion having an output end surface of an optical fiber is fixedly installed in a concave portion corresponding to an illumination window portion formed of a transparent resin member. Background technique [0002] Endoscopes are widely used in the medical and industrial fields. An object of diagnosis or an object of observation by an endoscope is a living body, an inside of a mechanical device, or the like. Therefore, in an endoscope apparatus, a light source for illuminating a diagnosis object or an observation object is required. [0003] A general endoscope device includes an endoscope and a light source device as an external device of the endoscope. The light source device incorporates a light emitting source such as a lamp for emitting illumination light or a light emitting element. [0004] The illumination light emitted from the light emitting source is transmitted thr...
