Abstract
Shown is a lens device 16 comprising a displaceable lens 18 and a guide 42, by means of which the lens is guided so as to be capable of being displaced. The lens device 16 comprises a first and a second galvanometric motor 46a, 46b and a first and a second force transmission device 54a, 56a; 54b, 56b, which is coupled to the rotor of the first and second galvanometric motor 46a, 46b, respectively, and which is coupled to the lens 18 at a first and second junction 58a, 58b, respectively. The force transmission device is suitable to convert a rotary motion of the rotor of the first and second galvanometric motor 46a, 46b, respectively, into a displacement motion of the lens 18. The first and the second junction 58a, 58b are thereby spaced apart from one another in a direction at right angles to the displacement direction of the lens 18.
