“…2), thereby photon energies and angles of incidence were varied. Hereby a total number of 11,153,574 X-ray photons were individually detected, analysed and digitally processed by the sensitive CCD camera of the PANTER facility, using a prototype the eROSITA satellite camera [4]. After evaluation of the measurement data, the two wideangle X-ray telescopes have an angular resolution of around four arc minutes (Fig.…”

“…3) and a focal length of around two meters. In direct comparison with the goldcoated telescope, the new chromium-iridium tri-layer mirror coatings bring in some energy ranges the X-ray light up to 30% more effective on the focus point [3,4]. The rich measurement datasets have been evaluated in detail, especially with regard to the imaging quality (on the optical axis and away from it), based on the analysis of individual focus images (Fig.…”

“…The 34 X-ray mirrors of the second telescope use an innovative tri-layer coating system made of chromium and iridium, which was applied in the Aschaffenburg coating laboratory [3]. Both telescopes work according to the bionic principle of a reflecting lobster eye [4]. The optics works with two consecutive reflections on mutually perpendicular mirror surfaces.…”

Lobster-eye type X-ray telescopes use reflecting plano mirrors under grazing incidence and can observe a large field of view. As part of a Bavarian-Czech cooperation, two telescopes were build, equipped with mirrors coated with gold and iridium. Their X-ray characterization was carried out at the PANTER test facility, which simulates parallel starlight incident on the telescopes. The telescopes have an angular resolution of about 4 arc minutes in X-rays and a focal length of about 2 meters. The used X-ray mirrors reflect and focus visible light as well; their functionality in the optical regime was checked in laboratory tests. Now another test campaign will be carried out to examine the telescope resolution for real objects of the visible night sky and the imaging properties for star constellations.

This chapter describes the history, principles, and recent developments of large field of view X-ray optics based on lobster eye designs. Most of grazing incidence (reflective) X-ray imaging systems used in astronomy and other applications, are based on the Wolter 1 (or modified) arrangement. But there are also other designs and configurations proposed for future applications for both laboratory and space environments. Kirkpatrick-Baez (K-B) based lenses as well as various types of lobster eye optics serve as an example. Analogously to Wolter lenses, all these systems use the principle that the X-rays are reflected twice to create focal images. Various future projects in X-ray astronomy and astrophysics will require large optics with wide fields of view. Both large Kirkpatrick-Baez modules and lobster eye X-ray telescopes may serve as solutions as these can offer innovations such as wide fields of view, low mass and reduced costs. The basic workings of lobster eye optics using Micro Pore Optics (MPOs) and their various uses are discussed. The issues and limiting factors of these optics are evaluated and current missions using lobster eye optics to fulfill their science objectives are reviewed. The Multi Foil Optics (MFO) approach represents a promising alternative. These arrangements can also be widely applied in laboratory devices. The chapter also examines the details of alternative applications for non-Wolter systems in other areas of science, where some of these systems have already demonstrated their advantages such as the K-B systems which have already found wide applications in laboratories and synchrotrons.
