ABSTRACT:
Laser treatment appliance having an illumination system, in particular for use in the field of medicine, has a laser light source for producing a treatment laser beam which is guided essentially freely, as well as an illuminating light source for producing a visible light for illuminating an area to be treated, and one or more first optical elements via which the treatment laser beam is passed on, with at least one of the first optical elements being in the form of an optical multifunction element, such that the visible light for illumination is also steered at least over this at least one optical multifunction element. The laser treatment appliance furthermore has an optical evaluation apparatus for diagnosis or analysis of radiation which is produced during the treatment process, and all the optical multifunction elements are designed such that they influence the treatment laser beam and the visible illuminating light essentially in an equivalent reflecting and/or transmitting manner. The laser treatment appliance furthermore has a beam splitter, which extends at least over the entire cross section of the treatment laser beam, for outputting the radiation, and which is arranged between the laser light source and the first multifunction element in the incidence direction of the treatment laser beam such that the visible light from the illuminating light source does not pass through it.
