This paper describes the technology of production and testing of mirrors for DAG Telescope (Doge Anadolu Gozlemevi) produced by Belgium Company AMOS. JSC LZOS fulfils works on production and testing of three mirrors: primary concave hyperbolic mirror of diameter 4 m, secondary convex hyperbolic mirror - 764 mm and tertiary elliptical mirror with flat working surface with dimensions 890x650 mm. The primary mirror is produced from Zerodur, while the secondary and the tertiary ones - from Astrositall. Some auxiliary elements, containers and handling tools, etc. are also produced at JSC LZOS. Special aspects of mirrors machining and testing are also reflected in this article.
