일부 실시예들에 따른 광학 장치는, 일방향으로 연장되는 배럴; 상기 배럴 내에 배치되는 복수개의 렌즈로 구성된 내부 광학계;및 상기 배럴의 상기 일방향 상의 단부에 배치된 보상 정렬 렌즈를 포함하되, 상기 내부 광학계는 상기 일방향에 대해 비스듬한 제1 광축을 갖고,상기 보상 정렬 렌즈는 상기 일방향에 대해 상기 제1 광축과 반대 방향으로 비스듬한 제2 광축을 가질 수 있다. A technical problem to be solved by a technical idea of the present invention is to provide a lens barrel assembly, an optical device, and a manufacturing method which have improved reliability. The optical device according to some embodiments includes: a barrel extending in one direction; an internal optical system composed of a plurality of lenses disposed in the barrel; and a compensation alignment lens disposed at an end unit on the one direction of the barrel. The internal optical system may have a first optical axis oblique to the one direction. The compensation alignment lens may have a second optical axis obliquely in the direction opposite to the first optical axis with respect to the one direction.
