Abstract
The GREGOR telescope of the Teide Observatory will be upon start of operations the first ground-based telescope with main optics made entirely of a silicon carbide composite material, namely, "carbon-fiber reinforced silicon carbide" or "Cesic(r)," a product of ECM, Germany. This paper describes the configuration and manufacturing of the GREGOR telescope's main optics: the primary (1.5 m), secondary (0.42 m), and tertiary (0.35 m) mirrors.
