    摘要： The invention relates to an imaging optical system (1) comprising a folding component (2) and a tunable optical component (3) that are arranged on an optical path of the optical system (1), wherein the tunable optical component (3) comprises a first optical surface (7), a second optical surface (8) and a deformable internal space (9) between the first optical surface (7) and the second optical surface (8), which internal space (9) is filled with a transparent liquid (11), wherein an optical property of the tunable optical component (3) is adjustable by altering a shape of the internal space (9). The imaging optical system (1) further comprises a moveably mounted cage element (13) that at least partly encloses the folding component (2) and is mechanically coupled to the tunable optical component (3) such that a displacement of the cage element (13) causes a change of the optical property of the tunable optical component (3) and an actuator (14, 15, 16) that is arranged between the folding component (2) and the cage element (13) and the actuator (14, 15, 16) is configured to exert a displacement force to the cage element (13).
