摘要： The invention relates to a device for machining an object by laser radiation, in particular by using the photodisruption method. Said device comprises an observation device for imaging the object and a laser scanning device by which the laser radiation is passed over a predetermined sector of the object for scanning said sector. According to the invention, such a device includes the observation device with a first lens for imaging the object; the laser scanning device with a second lens, through which the laser radiation is guided, in which both lenses with regard to the dimension of the regions to be produced in the images and/or with regard to their focal intercept are different from each other. This invention alternately images the respective region of the object in a first operating mode by the first lens and in a second operating mode by the second lens. It is thus possible to use in both operating modes a lens adapted to the intended imaging purpose.

摘要： A laser slit lamp comprising a slit lamp base, a slit lamp head and a slit lamp microscope. The laser slit lamp is connected with an applicator. It comprises a device for uniting radiation from at least two radiation sources collinearly and for directing the radiation of a treatment beam or working beam onto the location to be treated in or on the eye of a patient, a device for generating a target beam or marking beam for targeting and observing the location to be treated in or on the eye, and an adjusting device in the applicator for changing the intensity and diameter of the working beam spot used for treatment. The radiation sources are laser radiation sources arranged in the slit lamp head, in the slit lamp base or in the slit lamp microscope for generating the working beam, illumination beam and/or target beam. Devices for control, regulation and monitoring are likewise arranged in the interior of the slit lamp.

摘要： The invention relates to a method for forming curved cuts in a transparent material, in particular in the cornea, by the creation of optical perforations in said material using laser radiation that is focused in the material. The focal point is displaced three-dimensionally to form the cut by lining up the optical perforations. The focal point is displaced in a first spatial direction by a displaceable lens and said focal directions in such a way that it follows the contours of the cut, which lie on a plane that is substantially perpendicular to the first spatial direction.
