Accomplished the task of production of primary and secondary mirrors of Devasthal Optical Telescope under the project ARIES (India, Belgium, Russia): fabrication features

摘要

Basing on the contract with firm AMOS LZOS, JSC has accomplished the manufacturing works of the Primary andSecondary Mirrors of Devasthal Optical Telescope (DOT) for Aryabhatta Research Institute of Observational Sciences(ARIES). The Primary mirror specifications is as follows: diameter 3700 mm, vertex radius 14639 mm (F/1.96), conicalconstant -1.03296, asphericity 111 microns. The Secondary mirror specifications is as follows: diameter 980 mm, vertexradius 4675 mm (F/1.78), conical constant -2.79561, asphericity 47 microns. The results of works under this project arepresented in this paper.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
