摘要:
A device for testing the quality of microstructurization of a surface (2) having a known target microstructurization quality, comprising a radiation source (1) for coherent radiation, a first detector (10) and a second detector (4) and a masking system, all of which are set up and arranged with respect to one another so that radiation emitted by the radiation source (1) onto the surface (2) produces a diffraction pattern, wherein the diffraction maximum of order n of the diffraction pattern without the masking system would impinge on the first detector (10), the masking system prevents 80% of the photons that are assigned to the diffraction maximum of order n from impinging on the first detector and the diffraction maximum of order a of the diffraction pattern impinges on the second detector (4), wherein n is selected from the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 and a is selected from the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 and a≠n.

摘要:
In a process according to the invention and an apparatus according to the invention for the coating or modification of a surface a flow of a first gaseous phase or of a first aerosol comprising one or more precursor compounds is guided along a heated filament so that the precursor compounds are converted into reactive compounds. Alternatively, non-activated particles are guided along a heated filament so that these are activated and are then combined with a gaseous phase or an aerosol comprising a plurality of precursor compounds, so that the precursor compounds are thereby converted into reactive compounds. The reactive compounds formed according to at least one of the two aforementioned steps are guided onto a substrate that is exposed to atmospheric pressure, so that a layer is deposited on the substrate or its surface is modified.
