Method for forming a window as a security feature and object with a fluorescent window as a security feature.

摘要

The present invention relates to a method of forming a window as a security feature in an object. The window consists at least partially of at least one fluorescent material which is transparent in the visible wavelength range and is used as a security feature. As fluorescent transparent materials are single crystals, glasses, glass ceramics and / or ceramics available. The method discloses that monocrystalline materials with fluorescence properties are particularly suitable as security features and / or identification marks in measuring instruments, watches or ornaments. An exemplary suitable component consists of three plates (10, 11 and 14). Other variants with other numbers of platelets and other shapes are also available. In the example given here, the platelets (10, 11 and 14) are fluorescent and provided with polished and / or ground surfaces, so that the platelets can be joined together. The crystalline materials are cuboid-shaped with rounded corners, with polished and / or ground surfaces as required, which can be labeled (13) or decorated (12). Transparent fluorescent glasses, glass ceramics and / or ceramics are likewise usable for security features and / or identification marks.
