Abstract
An optical device includes: a first optical component that has an end face oblique with respect to a plane perpendicular to an optical axis; a second optical component that is optically coupled to the first optical component; and a lens that is placed between the first optical component and the second optical component, and is positioned so that the trajectory of a focal point formed when the first optical component and the second optical component rotate relative to each other falls within a valid region on the surface of the second optical component.
