  • Balanced optical system
    Patent number: 4764002
    Abstract: An optical element (10) is pivoted for limited rotation about an axis (12). An actuator arm (14) is rotatable by an actuator (13) about an axis (15) and is connected to the optical element by a first link (16). A second link (21) connects the actuator arm (14) to a balance arm (18) which carries a balance mass (20) and is pivoted about an axis (19). The arrangement is such that the line (23) joining the axis (12) of the optical element to the point of connection between the first link (16) and the optical element (10) is always parallel to the line (24) joining the axis (19) of the balance arm (18) to the point of connection between the balance arm and the second link (21).
