Zusammenfassung: | A device for the temperature-dependent axial movement of an optical component including a monolithic mounting unit having an outer mounting part forming a fixed holder having an axis and an inner mounting part forming a mount adapted to support the optical component. The mount is movable along the axis. A moving mechanism is connected to the fixed holder and the movable mount. The moving mechanism includes at least one external expansion element including a first material having a first coefficient of thermal expansion and at least one internal expansion element including a second material having a second coefficient of thermal expansion, where the first coefficient of thermal expansion is larger than the second coefficient of thermal expansion. A number of connecting links is disposed in a star-shaped formation and join a respective one of the at least one external expansion element to a respective one of the internal expansion element. Each connecting link is disposed at a prescribed pitch angle with respect to the axis that differs from 90°. |
