Patent ID: 8340489

Claim:
A device for adjusting a position of an optical component in two directions, comprising: a first member ( 110 ) having a flat sliding surface ( 111 ), a second member ( 120 ) arranged to be movable relative to the first member in contact with said sliding surface, to which second member the optical component is attachable, and an elongated third member ( 130 ) arranged in an operational connection with the first and the second member so that the second member is movable relative to the first member in a direction of a rotation axis of the third member when the third member is being moved in the direction of its rotation axis, said rotation axis being substantially parallel to the sliding surface of the first member, characterised in that the third member comprises an eccentric part ( 132 ) which is eccentric in relation to the rotation axis of the third member, the eccentric part being arranged in an operational connection with the second member so that the second member is movable relative to the first member in a direction perpendicular to said rotation axis when the third member is being rotated around its rotation axis.
