Techniques are described in this paper  including the bonding procedure of silicon carbide to form a mirror shape  the CCOM technology for aspheric grinding  polishing on a home-developed tool -FSGJ-2  and the aspheric profilometry. A specialized Offner Null lens is also developed to measure the aspherical mirror with laser interferometer. With the technology depicted in the paper  a 502mm 298 mm off-axis SiC aspherical mirror is successfully made with a surface accuracy better than 1/50rms  the final result meets the design requirement.

With the development of diffraction optics  computer technology  and micro-processing technology  the accuracy of the CGH testing can achieve a hundredth of a wave  and the cost is reduced greatly. CGH is capable of producing an optical wavefront with any desired shape. So it is fascinating and will have good prospects to test free-form surfaces using CGH. As the CGH can create any wavefront shape  it can also be used in unsymmetrical aspherical surfaces testing. Taking the cubic surface as an example  this paper gives a method to test unsymmetrical surfaces. This paper gives the design to test a cubic surface. And the separation of the diffraction orders and the binary process of the continuous CGH phase function are discussed in detail. The alignment tolerance of the test system and the CGH fabrication tolerance are analyzed. We also present an idea using a CGH and two spherical lenses as null lens to test the cubic surface when the surface deviation is great. 2011 IEEE.   Investigation of Sub-aperture Polish Techniques for Manufacturing Astronomical Mirror 会议论文  OAI收割 San Diego, California, USA, 2010-6-27 作者:  Jiang Zi-bo;  Li Xin-nan;  Zheng Yi;  Guo Wei-yuan;  Liang Bin 收藏  |  浏览/下载：24/0  |  提交时间：2014/01/03 Aspheric mirror  optical manufacture  computer control optical surface  ion beam figuring
