Abstract

The Central-Axis Reflector (ZAS), the design of which is presented, is a segmented mirror telescope. The inventions relate mainly to the optical system and to the tracking apparatus. A number of individual mirror bodies, ground off-axis (hexagonal/polygonal) produce one primary mirror with closed circular aperture when joined together. The overall design of the tracking apparatus results directly (and thus without unnecessary adornment) from the two planes of motion which have been reduced to an obligatory minimum but which are required for tracking of the telescope.
