Asphericity which affects the manufacturing process and the grinding quantity is an important parameter of optical aspherics. In this paper  the approximation  the least square fitting  wavefront aberration  sag methods are given for the calculation of optical asphericity. The effects of different definitions of optical asphericity are analysed to optimize the process of manufacture. A sag method is presented to solve the best-fit sphere and asphericity for an off-aixs aspheric mirror with a rectangle aperture of 180mm145mm  and polishing quantity and distribution plots are given. The optical manufacturing and testing technology for different choices of best-fit spheres and asphericity are described and analyzed. Therefore  proper definition of optical asphericity which is useful to manufacturing is very important for optical fabrication and test. 2009 SPIE.

Micro-crack is one of the most effective factor to the intensity and service life of optical components. Owing to the micro-crack on surface  actual strength of optical components is reduced severely  even less than ten-percent of its theoretical strength. According to fracture mechanics  the mechanisms of the formation and propagation of micro-crack and the growth theory of sub-critical micro-crack are discussed in the paper firstly. Based on practice  an on-line test method disposing etching holes-the molecule-infiltrating method and the principles of acid-etching method disposing micro-crack are described. Followed by the demolishing mechanism of abrasives and a more reasonable removal redundancy of fine-grinding and polishing during  optical production is given by using abrasives in different-size orderly. 2009 SPIE.

Electrostatic membrane reflector (EMR) is very promised for optical quality application with the merits of utra-lightweight and flexible. Configuring a circular membrane reflector with electrostatic potentials exerted on distributed electrodes can approximatively produce a parabolic shape. A 300mm EMR (made from polyimide) stretched by distributed electrodes below is designed  and the number of concentric electrodes needed for membrane shape forming is analysed. First  based on an analytical solution of Poisson's equation  determine the membrane control matrix by finding influence functions of 3 concentric electrodes and 6 control points on membrane surface in order to compute the needed voltages exerted on the distributed electrodes by the method of least-squares fitting. Then the final shape solved by finite element analysis with ANSYS is contrasted with the paraboloid and deviates greatly when the central displacement of membrane is beyond 2.5mm  but in this range increasing the number of electrodes and control points will get a better shape. The corresponding errors are analyzed  and the control method is concluded. Only using the integrated method of analytical computation  numerical analysis and experiment  the membrane shape of certain central displacement can be exactly predicted and controlled. 2009 IEEE.
