Description
上記課題を解決するために、この発明は以下の手段を提案している。
本実施態様にかかる内視鏡装置は、被検体の内部を観察するための内視鏡装置であって、前記被検体の内部に挿入される挿入部と、前記挿入部を前記被検体に挿入する挿入方向の先端に配置され、前記被検体の内部の画像を取得するための撮像光学系が収められた鏡筒と入射光量を調整するための絞りとを有する画像取得部と、を備え、前記画像取得部は、前記撮像光学系の像面側から前記絞りに向けて検査光を照射する検査光源を前記画像取得部の内部に挿入するために、前記鏡筒の外壁を貫通して形成された検査孔を備えることを特徴とする。
In order to solve the above problems, the present invention proposes the following means.
An endoscope apparatus according to this embodiment is an endoscope apparatus for observing the inside of a subject, and includes an insertion portion that is inserted into the subject, and the insertion portion is inserted into the subject. An image acquisition unit that is disposed at the distal end in the insertion direction and includes a lens barrel that stores an imaging optical system for acquiring an image inside the subject, and an aperture for adjusting the amount of incident light. The image acquisition unit is formed through the outer wall of the lens barrel in order to insert an inspection light source for irradiating inspection light from the image plane side of the imaging optical system toward the diaphragm. The inspection hole is provided.
