Title: Christoph Braatz: Innovator in Transparent Material Technologies
Introduction
Christoph Braatz is a notable inventor based in Hainburg, Germany. He has made significant contributions to the field of transparent materials, holding a total of 3 patents. His work focuses on enhancing the properties of transparent substrates through innovative layering techniques.
Latest Patents
One of Braatz's latest patents is for a pane of transparent material having a low emissivity. This invention involves a system of layers applied to a transparent substrate, which includes a first layer of an oxide such as ZnO or SnO₂, a second layer of a substoichiometric oxide of Zn or Ta, a third layer of Ag or Cu, a fourth layer of a substoichiometric oxide of Ti, Cr, or Nb, and a fifth layer similar to the first layer. The layers are preferably deposited by magnetron cathode sputtering in an atmosphere consisting of inert gas and, in the case of the oxide layers, a reactive gas. Another significant patent is for an optical filter having a multi-layer coating. This coating is designed for a material that is highly transparent to visible light, with an emissivity of e<0.04 and a light transmission of T≥78%. It features two silver layers of different thicknesses, three oxide coatings, and very thin metal or metal suboxide coatings as blockers, with the oxide layers being alloys of metals such as SnMg, SnAl, SnZr, SnTi, or SnTa.
