Currently, the main mirror modernized by the opticians of Shvabe Holding Company is being mounted on the Large Altazimuth Telescope (BTA) in the Special Astrophysical Observatory of the Russian Academy of Sciences. This jumbo article will allow to three times improve the key optical characteristics of the Russian telescope.
Modernization of a 6-meter article weighing 42 tons was being carried out at Lytkarino Optical Glass Plant (LZOS), an enterprise of Shvabe Holding, for 10 years. The use of the advanced high-precision processing and control technologies for large-sized optics allowed LZOS specialists to increase more than three times the angular resolution of the BTA main mirror.
"The processing of astromirrors with nanometric accuracy is one of Shvabe unique technologies, which allows to successfully implement astronomic projects on all continents. The work successfully completed by the specialists of the holding company will allow BTA to be among the top ten world's leading telescopes for reflective optical characteristics and reliably work for Russian science for several decades," said Alexey Patrikeyev, Shvabe Director General.
The installation of the mirror is scheduled to be completed by early September. Right after that, the first astronomic studies using the modernized telescope will start in Karachay-Cherkess Republic.A Large Altazimuth Telescope (BTA) was built in the mountains of Karachay-Cherkessia in the territory of the Special Astrophysical Observatory of the Russian Academy of Sciences in 1975. Its weight is 850 tons.
