<p>An apparatus for controlling optical system inclination/rotation center, comprising a housing (200); a bracket (201) installed in the housing (200) for loading lenses; and a first spring system (202) and a second spring system (203) connected onto the housing (200) and the lens bracket (201), wherein either one of the spring systems is a planar spring system and comprised of at least one leaf spring, the surface of each leaf spring being generally parallel to the plane of the spring system; the planes of the first spring system (202) and the second spring system (203) being generally parallel with each other, and the normal direction of each spring system being generally parallel to the center axis of the lens bracket (201) or the lens optical axis; the effective elastic coefficient of said first spring system (202) in the lens axis direction is far less than that in the direction perpendicular to the lens axis; the effective elastic coefficient of the second spring system (203) in each direction is far less than that of the first spring system in the same direction.</p> |
