| description | The arrangement includes at least two lenses or lens groups arranged on a common optic axis, which are coupled with piezoelectric or electro-restrictive, linear drives, whereby an active material surface area, undergoing micro-deformation, faces a passive material surface area. At least one of the linear drives comprises two parallel, active material surface areas, between which the passive material surface areas are arranged. The arrangement includes at least two lenses or lens groups arranged on a common optic axis, whose positions are individually or commonly in direction of the optic axis, adjustable in reference to an assembly group connected firmly with an optic instrument. The lenses or lens groups are coupled with piezoelectric or electro-restrictive, linear drives to provide a position change, whereby an active material surface area, undergoing micro-deformation, faces a passive material surface area, and whereby a movement of both material surface areas is triggered with respect to each other. At least one of the linear drives comprises two even, parallel to each other arranged, active material surface areas, whose micro-deformations are directed towards each other, and between which the passive material surface areas are arranged. The active material surface areas are triggered simultaneously, whereby the micro-deformations of both active material surface areas are directed simultaneously towards the passive material surface areas. |
