    Abstract: A method of detecting defects present at the surface and/or internally in transparent materials, particularly of detecting included foreign bodies or bubbles in glass, is disclosed. The test material is scanned with an electromagnetic radiation of a single wavelength which is set to the penetration depth in the test material. The intensity reflected by the defects is picked up and analyzed. By this method only defects located up to a specified depth in the material are detected. Visible light as well as UV- or IR radiation may be applied. The associated test rig comprises a tunable Laser (2), a conveyor belt (6) carrying the test material (5), a fast rotating mirror-wheel (3) which directs the light beam (4) at high speed over the test material (5), and an optical sensor (7) connected with an analyzer unit (8).

    Abstract: Glass-ceramic is provided that is at least partly provided with a hard material layer to protect against external mechanical influences. The hard material layer contains at least two phases, which are present side by side and are mixed with one another. The at least two phases include at least one nanocrystalline phase and one amorphous phase. The hard material layer has a hardness of at least 26 GPa and a layer thickness of at least 0.5 μm. The hard material layer is chemically resistant in the temperature range from 200° C. to 1000° C. The coefficient of thermal expansion (α) of the glass-ceramic does not differ by more than +/−20% from the coefficient of thermal expansion (α) of the hard material layer.

    Abstract: To lead an optical waveguide through a housing wall, the optical waveguide is, in one section freed of its protective layer and hermetically connected in a bushing by glass soldering it to the bushing. In at least one load-relieving section leading out of the bushing, the optical waveguide is fastened by its protective layer to an extension of the bushing. The bushing is hermetically set into the housing wall.
