Rail, Zdeněk ; Franců, Helena ; Ulrichová, Iva ; Šípová, Gabriela ; Vápenka, David ; Vávra, Emil
This paper introduces several types of optimized off-axis mirror systems. Systems without central shading and color defects provide high-contrast imaging. They are suitable for use as astronomical telescopes or as precision laboratory collimators of parallel light beams. Many of these devices have been designed and constructed for various purposes in the Development Optical Workshop of the Academy of Sciences of the Czech Republic.
