ABSTRACT:
The invention relates to micromechanical mirrors with a high-reflection coating for the deep-ultraviolet (DUV) and vacuum-ultraviolet (VUV) spectral range, based on a substrate which is coated with an aluminum layer and a transparent blooming coating. Likewise the invention relates to a method for the production of such micromechanical layers with a high-reflection coating and to the use thereof for the production of microsensors, optical data stores or video and data projection displays.
