This optical system can be used both in infrared and visible configurations. The designing of this system is based on an on-axis three-mirror anastigmatic (TMA) system. Here the on-axis concept allows wide field of view (FOV) enabling a diversity of designs available for the Multi-Object Spectrometer instruments optimized for low scattered and low emissive light. The available FOVs are upto 1 in both spectrum ranges  whereas the available aperture range is F/15 - F/10. The final optical system is a three-mirror telescope with two on-axis and one off-axis segment and its resolution is 0.3m or even lower. The distinguished feature of this design is that it maintains diffraction-limited image at wide wavelengths. The technological developments in the field of computer generated shaping of large-sized optical surface details with diffraction-limited imagery have opened new avenues towards the designing techniques. Such techniques permit us to expand these technological opportunities to fabricate the aspherical off-axis mirrors for a complex configuration.   The ELT situation in China 会议论文  OAI收割 Retirement Symposium for Arne Ardeberg on Extremely Large Telescopes - Which Wavelengths, Lund, SWEDEN, 2007-11-29 作者:  Liu Z(刘忠);  Cui, XQ;  Liu Z(刘忠) 收藏  |  浏览/下载：12/0  |  提交时间：2016/04/06 Extremely Large Telescope  ground based  segment  ring aperture  Interferometric Telescope  active  optics  adaptive optics  spherical mirror  site survey  Dome A   Some considerations about structure of off-axis segments in stitching paraboloidal mirror 会议论文  OAI收割 Xian, China, 2005-11-2 作者:  Gao Bilie 收藏  |  浏览/下载：10/0  |  提交时间：2013/12/24 aspherical manufacture  structure of off-axis segment  stitching paraboloidal mirror  rotating axis of off-axis segment  reminder removal quantity   Analysis of alignment error in asphere testing using a corrector (EI CONFERENCE) 会议论文  OAI收割 Optical Design and Testing II, November 8, 2004 - November 11, 2004, Beijing, United states 作者:  Xue D.-L.;  Zhang X.-J.;  Zheng L.-G. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 The characteristics and effects of alignment error on test results are analysed in this paper. The mathematical model are established  the least square method is used to determine the misalignment. Procedures are presented that allow for separation of misalignment from misfigure in asphere testing. The misalignment-induced aberrations by corrector and the support of the mirror can be calculated and subtracted from segment interferogram so that only true misfigure remains. The accuracy of the system can reach up to 0.028(=632.8nm).   Current Progress in the Research of LAMOST Primary Mirror Support 会议论文  OAI收割 Glasgow, Scotland, 2004-6-21 作者:  Xiangqun Cui;  Xuefei Gong 收藏  |  浏览/下载：18/0  |  提交时间：2013/12/23 Segment mirror  Mirror cell  Truss  Finite element analysis
