Abstract

The current invention relates to an electrically actuated device for orientating an optical element around a rotational axis comprising a rotor and a stator, said rotor comprising said axis, said axis comprising an optical end and an electronic end, the stator comprising a means for generating a magnetic field; the device further comprising a first axial rotation bearing associated with said optical end and a second axial rotation bearing associated with said electronic end, each bearing comprising an inner part and an outer part; said device further comprising electronic actuation means for providing a charged particle having a velocity v moving through a conductor provided on said rotor, wherein the axis is able to perform a rotational movement over less than 180°, and whereby the orientation of said axis is controlled by a Lorentz force resulting from said charged particle moving in said magnetic field; wherein said device comprises axis-related clamping means configured to exert an axial force on the inner parts of the bearings toward each other for axially clamping said axis, thereby radially fixating said axis with respect to each of the inner parts of the bearings.
