The present invention provides a device (100) for adjusting a position of an optical component in two directions. The device comprises a first member (110) having a flat sliding surface (111), and a second member (120) arranged to be movable relative to the first member in contact with said sliding surface. The optical component can be attached to the second member. The device also comprises 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.The rotation axis is arranged to be substantially parallel to the sliding surface of the first member. The third member comprises an eccentric part (132) which is eccentric in relation to the rotation axis of the third member. The eccentric part is 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.The invention also provides a method for adjusting a position of an optical component in two directions.

La présente invention concerne un dispositif (100) permettant de régler la position d'un composant optique dans deux directions. Le dispositif comprend un premier élément (110) comportant une surface coulissante plane (111) et un deuxième élément (120) monté mobile par rapport au premier élément en contact avec ladite surface coulissante. Le composant optique peut être fixé au deuxième élément. Le dispositif comprend également un troisième élément allongé (130) disposé en relation opérationnelle avec le premier et le deuxième élément de sorte que le deuxième élément est mobile par rapport au premier élément dans une direction d'un axe de rotation du troisième élément lorsque le troisième élément est déplacé dans la direction de son axe de rotation. L'axe de rotation est orienté de manière sensiblement parallèle à la surface coulissante du premier élément. Le troisième élément comprend une partie excentrée (132) qui est excentrée par rapport à l'axe de rotation du troisième élément. La partie excentrée est disposée en relation opérationnelle avec le deuxième élément de sorte que celui-ci est mobile par rapport au premier élément dans une direction perpendiculaire audit axe de rotation lorsque le troisième élément tourne sur son axe de rotation. L'invention concerne également un procédé de réglage de la position d'un composant optique dans deux directions.
