Experts of the Fraunhofer IST explain fundamentals and specialized questions, among other things from the field of thin film technology.
I have taken the seventieth birthday of the Fraunhofer Gesellschaft in 2019 as an opportunity to take a closer look at the quantum leap. After all, the famous Fraunhofer lines which are direct consequences of quantum leaps. Around 1814 our namesake Joseph von Fraunhofer discovered around 570 mysterious black lines in the emission spectrum of the sun. He catalogued them meticulously, but was unable to explain their origin; this would have indeed been impossible back then, without the modern physics of the 20th century. If, for example, sunlight is broken down into its spectral colors through a high-resolution optical grating, “the corresponding colors are missing at the positions of the Fraunhofer lines”.more info
