Abstract: A chromatic, confocal measuring device uses a broadband, high-intensity light source implemented by optically pumping a luminophore. The illumination of the luminophore is selected so that the properties of the luminophore are exploited to maximize the optical output power of the light source.

Abstract: The invention relates to a levitation melting process and a device for producing castings with movable induction units. In this process, induction units are used in which the opposite ferrite poles with the induction coils are movable and move in opposite directions. In this way, the induction units for melting the batches can be arranged close together in order to increase the efficiency of the induced magnetic field. When casting the molten batch, the induced magnetic field is reduced by increasing the distance between the ferrite poles with the induction coils, thus preventing the melt from touching the ferrite poles or the induction coils.

Abstract: The invention relates to a levitation melting method and an apparatus for producing casting bodies with tilted induction units. During this method, induction units are employed in which the opposing ferrite poles with the induction coils are not arranged lying in one plane, but tilted at a determined angle to the levitation plane. In this way, an increase in efficiency of the induced magnetic field for melting the batches can be achieved with the induction units. The tilted arrangement increases the portion of the induced magnetic field that effectively contributes to the holding force of the field for levitation of the melt.
