Progress in lobster-eye x-ray optics development

The Lobster-eye optics represents a promising way of very wide field X-ray imaging with numerous applications especially in future X-ray astronomy projects and in fast yet sensitive monitoring of X-ray sky. We report on recent developments in design and construction of wide-field optical elements of Schmidt and Angel geometry. New compact Lobster-eye modules with both geometrical arrangements have been developed and tested. They feature improved parameters such as surface quality and angular resolution. Computer ray-tracing and first experimental results obtained in visible and X-ray regions are presented.
