  • Patent number: 8416399
    Abstract: A method for determining the surface topography of a coated object and for the simultaneous spatially resolved determination of the thickness of the layer on the coated object. It is provided that the surface topography is measured with the aid of white-light interferometry, the thickness of the layer is measured by the principle of reflectometry, and by using, for both measurements, a shared radiation source having an electromagnetic radiation spectrum, which is reflected from the layer surface in a first wavelength range contained in the radiation spectrum and which penetrates into the layer in a second wavelength range contained in the radiation spectrum. Also described is a corresponding optical measuring instrument. The method and the optical measuring instrument make simultaneous highly accurate surface measurement of the surface topography and of the layer thickness of coated objects possible.

  • Publication number: 20090039547
    Abstract: A method for producing an object including at least one autonomous part movably disposed relative to an affixing part includes: providing a mold having at least one cavity configured to produce the at least one autonomous part; filling the at least one cavity with a curable or solidifying molding compound that includes a pulverulent sintering material and a binder; allowing the molding compound to solidify so as to form the at least one autonomous part; removing the at least one autonomous part from the cavity; disposing the at least one autonomous part in or on the affixing part so as to form a preform; and heat treating the preform so as to form the object.
