摘要 |
The present invention relates to a method for forming a light diffraction window in at least one defined area of an object in order to generate light emissions in this area in the case of one or more visible wavelengths, and to an object, particularly a component for a measuring instrument, for example a watch hand, which fully or partially consists of fluorescing or phosphorescing optical materials with waveguide properties and the cross-section, geometric shape and specific surface structure of which are manufactured in a special way for the purpose of optimising the optical properties or blocking the light. |
