Abstract

The central-axis reflector (LAS) , the design principle which is pre-sented below is a segmented-mirror telescope.The inventions relate main-ly to the optical system and to the tracking apparatus. A large number of small 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 a minimum but which are required for tracking of the telescope.
