Optical mounting and optical component comprising said type of optical mounting
The invention relates to an optical mounting comprising a stationary outer mounting and an inner mounting part embodied to receive an optical element. The aim of the invention is to enlarge the adjustment path in the direction of the optical axis of the optical element that is to be mounted, and as a result, obtaining high stability and rigidity that is perpendicular to the optical axis. Also, the invention aims at keeping the space requirements and the manufacturing and mounting costs as low as possible.
1. An optical mount comprising a stationary outer mount and an inner mount piece that is adjustable relative to the outer mount and that serves to receive an optical element, wherein said inner mount piece is enclosed by elastic annular disks, which are disposed coaxially with respect to one another in one plane, and which are connected to one another, to the inner mount piece and to the outer mount via bending beams in such a manner that a rigid body motion of the inner mount piece is generated in the direction of the optical axis, and wherein the bending beams are connected to the outer mount and to the inner mount piece at three points, the bending beams are disposed so as to be staggered relative to one another by 120°, and the bending beams are designed in such a manner that their rigidity in the direction of the optical axis is relatively low and their rigidity in all other directions is relatively high.
2. The optical mount as in claim 1 , wherein the outer mount, the inner mount piece and the elastic annular disks are integrally formed in one piece.
3. The optical mount as in claim 1 , wherein the elastic annular disks are nested one inside the other.
4. An optical assembly comprising an optical element in an optical mount according to claim 1 , wherein the bending beams are connected to the outer mount and to the inner mount piece at three points, the bending beams are disposed so as to be staggered relative to one another by 120°, and the bending beams are designed in such a manner that their rigidity in the direction of the optical axis is relatively low and their rigidity in all other directions is relatively high; and
wherein the optical mount with the mounted optical element is fitted into a tubular carrier having actuating means disposed outside the effective range of the optical element, which actuating means act on the inner mount piece and in that measuring elements for measuring the adjustment path in the direction of the optical axis of the optical element are attached to the tubular carrier.
5. The optical assembly as in claim 4 , wherein the actuating means used are actuating motors, which are disposed so as to be staggered relative to one another by 120° and which act on the inner mount piece via spindles.
6. The optical assembly as in claim 4 , wherein the actuating means used are piezo elements which act on the inner mount piece via levers.
