Abstract

Chinese astronomical community has suggested to construct a high resolution precision and wide field survey of universal optical / infrared telescope, suitable for a wide range of cutting-edge scientific research subject. The telescope diameter is 12 meters, and it is composed of 84 pieces of hexagonal mirrors. After the completion, it could be a world's largest telescope. Its wide field survey function will be work together with the 30 meters telescope in the near future on the observation of complementary. The telescope optical system adopted innovative design ideas, its multiple focuses can achieve rapid switching; its atmospheric dispersion corrector lens-prism can correct aberration also, and with the advantage of simple structure; two layers of Nasmyth platform can be placed more scientific instruments. LAMOST, a Chinese large spectrum survey telescope has been built and put into operation many years, it has successfully developed the two segmented optical mirrors and one of them is with deformation of thin mirror active optical technology, as well as the batch grinding hexagonal off-axis mirror technology developed in recent years, for construction of the 12 meters telescope laid a good technical foundation.
