An artificial eye lens having an integral optical part which has, viewed in the direction of an optical principal axis of the eye lens, a first optical side and an opposite, second optical side. The optical part is formed with a structure having birefringence, where the birefringent structure in the integral optical part is formed as a laser structure. A method for producing an artificial eye lens, where the birefringent structure is produced with a laser apparatus, and a pulsed laser beam having a pulse length of between 100 fs and 20 ps, a wavelength of between 320 nm and 1100 nm, a pulse repetition rate of between 1 kHz and 10 MHz, a focus diameter of less than 5 &#x3bc;m, and a power density of greater than 10W/cm.

Artificial eye lens with laser-generated birefringent structure and method for producing an artificial eye lens

The invention relates to an artificial eye lens comprising an optical part, which has a first optical side as viewed in a direction of an optical principal axis of the artificial eye lens and an opposite second optical side, wherein a structure with at least one depression is formed in a haptic arrangement of the artificial eye lens and/or in a surround that surrounds the optical part at least in certain areas and that differs from the haptic arrangement, wherein the structure is formed as a micro-perforation with a multiplicity of perforation zones and at least some perforation zones are filled at least in certain areas with at least one medicament for the purposes of producing a medicament repository. The invention also relates to a method for producing such an artificial eye lens.

An artificial eye lens () having an optical part () which has a first optical side () and an opposite, second optical side (). The optical part () has a diffractive grating structure that contributes to an optical imaging property of the optical part (). The diffractive grating structure is an amplitude grating () formed in the optical part () as a laser structure. A method for producing an artificial eye lens () where the amplitude grating () is produced with a laser apparatus (), and a pulsed laser beam () having a pulse length of between 100 fs and 20 ps, a wavelength of between 320 nm and 1100 nm, a pulse repetition rate of between 1 kHz and 10 MHz, a focus diameter of less than 5 &#x3bc;m, and a power density of greater than 10W/cm.

The invention relates to stereoscopic display system having a single display (). Right and left partial images are sequentially displayed on the display (). For the viewing, two separate component beam paths () for viewing only left partial images () and only right partial images () and a switchover device () are provided. The switchover device () couples in the data, which is shown on the display, from a common part of the viewing beam path alternately into the two separate component beam paths in synchronism with the display of the right and left partial images on the display. In one embodiment, the switchover device includes a polarization switch () and a polarization beam splitter (). The polarization switch () is arranged either in the illuminating beam path or in the common part of the viewing beam path.

Stereoscopic display system having a single display

An OCT-supported surgical system includes an OCT module that includes a surface scanner, the position of which can be sensed by a position sensing unit, and an evaluation and display unit, which is connected to the OCT module and to the position sensing unit in order to be able to correlate a tissue-differentiated tomogram of a specimen sensed by the OCT module with preoperatively produced specimen data.

Surgical system supported by optical coherence tomography

In an apparatus for the image-supported treatment of a work object with a work object data unit and a display unit for the display of work object data from the work object data unit, the display unit makes possible a simultaneous visual sensing, with freedom of head movement, of the instantaneous work object and of the work object data from the work object data unit.

Apparatus for image-supported treatment of a work object

An electronic level comprising a clinometer, an image receiving device having a telescope with an objective and with a CCD receiver matrix and with a screen for displaying the image of a graduated staff which is set up at a target and provided with a coded graduation. A vertical axis is rotatable about the level. A leveling device is included for alignment and rough leveling of the level with respect to the graduated staff. An input unit is provided for entering measurement data. A power supply unit and a computer is included for processing the measurement data, calculating measurement values and for image evaluation. The image receiving device comprises a CCD receiver matrix which is preferably operated in video clock. The objective or the CCD receiver matrix is arranged in a fixed position relative to the vertical axis, and objective and CCD receiver matrix are adjustable relative to one another, and the clinometer is assigned in a fixed manner for measuring the deviation of the position of a sighting axis relative to the horizon, wherein the sighting axis is formed by a center pixel of the CCD receiver matrix.
