摘要

This optical device comprises an optical element (1) that has a rotatable optical functional surface (2), a base (3) that supports said optical element (1), and a package (4) that contains the optical element (1) and the base (3). The package (4) comprises a wall section (5) that surrounds the optical element (1) and the base (3), a light-transmitting window section (7) that seals one opening (6a) in the wall section (5) and forms an optical path for the optical functional surface (2), and a bottom plate (8) that seals the other opening (6b) in the wall section (5).
