Thereby we show and discuss some experimental results and correlate them with simulations. Preliminary results of an ongoing study on other strange animal mirror eyes with potential scientific and technical applications are also discussed. Some of them are based on the principle of multilayer multi-mirror active optics arrangements. The Lobster Eye X-ray optics needs special reflective coatings for a better performance, which are currently developed within the Bavarian-Czech cooperation project JEUMICO.}, subject = {R{\"o}ntgenastronomie}, language = {en} } @inproceedings{SkalaDoehringHudec2017, author = {Skala, Petr and D{\"o}hring, Thorsten and Hudec, Rene}, title = {Colors of the universe - market study on optical filters for professional astronomy}, series = {DGaO-Proceedings}, volume = {2017}, booktitle = {DGaO-Proceedings}, number = {2017}, publisher = {DGaO}, organization = {Czech Technical University in Prague}, issn = {1614-8436}, pages = {2}, year = {2017}, abstract = {For astronomers, filters are essential observational tools and in many cases, it is hard for them to find the best supplier.

The sputtering parameters are optimized in the context of the expected re ectivity of the coated X-ray mirrors.
