An ophthalmological apparatus includes a base station having a light source generating light pulses, and an application head mountable on an eye having a light projector for focussed projection of the light pulses for punctiform breakdown of eye tissue. The application head has movement drivers moving the light projector in a feed direction and a first scanning direction. A scanner in the base station deflects the light pulses in a second scanning direction. The ophthalmological apparatus includes an optical transmission system transmitting deflected light pulses from the base station to the application head, and superimposing the light pulses deflected in the second scanning direction onto the movement of the light projector in the first scanning direction. Light sources with high light pulse rates, for example femtosecond lasers may be used, without impractical enlargement of the size of the application head.

An opthalmological apparatus includes a base station having a light source for generating light pulses, and an application head mountable on an eye having a light projector for the focussed projection of the light pulses for punctiform breakdown of eye tissue. The application head has drivers for moving the light projector in a feed direction and in a first scanning direction. A scanner is arranged in the base station in order to deflect the light pulses in a second scanning direction. The opthalmological apparatus includes an optical transmission system for transmitting deflected light pulses from the base station to the application head, and for superimposing the light pulses deflected in the second scanning direction onto the movement of the light projector in the first scanning direction.

An opthalmological apparatus () comprises a base station () having a light source () for generating light pulses, and an application head () which can be mounted on an eye () having a light projector () for the focussed projection of the light pulses for punctiform breakdown of eye tissue (). The application head () additionally has movement drivers () for moving the light projector () in a feed direction and in a first scanning direction. A scanner () is arranged in the base station () in order to deflect the light pulses in a second scanning direction. In addition, the opthalmological apparatus () comprises an optical transmission system for transmitting deflected light pulses from the base station () to the application head (), and for superimposing the light pulses deflected in the second scanning direction onto the movement of the light projector () in the first scanning direction. It is possible to use light sources with high light pulse rates, for example femtosecond lasers, without the need for impractical enlargement of the overall size of the application head () owing to the scanner. In addition, it is possible while safeguarding a manageable overall size of the application head () to make use of light sources with high light pulse rates, something which increases the accuracy of treatment and reduces the burden on the eye ().

The invention relates to embodiments of an optical system for luminescence determination, comprising two or more excitation light sources, a sensor platform and an optical component with several discrete facets for beam deflection towards the sensor platform.

In a method for robot-controlled cutting of workpieces to be joined by laser radiation, a first workpiece is arranged in vicinity of a second workpiece in a first position. A laser is focused onto the first workpiece. A contour of the first workpiece is cut with the laser beam; this contour is to be assembled and joined with the second workpiece. During cutting, a first spacing of a focal point of the laser beam from the second workpiece is repeatedly determined in a distance direction that is identically oriented during cutting and is adjusted to a direction of assembling the first and second workpieces. During cutting, a second spacing of a processing point of the laser beam from the second workpiece is maintained at a constant value.
