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.

Aspheres are utilized widely thanks to the development of optical design
manufacture and testing. Compensators are usually necessary when aspheres are under test. The alignment of aspheres and their compensators is a risk because it's tough to check whether the compensators work in right way. A new method of alignment with four poles is put forward in this paper. Optical interval error can be tight while it is quite important due to direct influence on central curvature
conic constant and high order coefficients of aspherical surface. A modified on-axis Foucault apparatus is set up since it makes the optical axis visible and helps to control the error of off-axis amount. Some small holes are drilled in the metallic cell of the compensator so that the ends of poles can be stably relied on in order to increase operational repeatability. The method has been carried out practically and it matches the measurement result given by a set of theodolites. 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.

Based on the characteristics of off-axis aspherical surface
the comparison of simulation effects under different parameters is made. In order to achieve optimal parameters
a new method used for polishing off-axis aspherical mirrors-Double-Swing Method (DSM) is proposed in this paper
a high order off-axis rectangle aspherical mirror has been polished by DSM. The final result of profile measurements of 12nm
and the polishing mechanism of DSM is introduced. The mathematical model of the DSM with steady movement state is established.The movement of this mathematical model is simulated in a programming language
RMS is achieved. The result indicates that the method is of practice and has even higher working efficiency and precision. 2009 SPIE.

Testing of mid-frequency surface error is of the first importance for fast optics
especially for large aperture aspherics. Foucault test plays a dominant role for surface error inspection before the digital interferometer age
but it seems to have faded out these days because no quantitative results turn out. However
an interferometer with high resolution CCDs is either unavailable or unaccessible in the process of manufacture. As its advantages are realized and recognized for the second time
Foucault test is going back to the stage again. A new theory of calculating the contrast of the shadow pattern of Foucault test is put forward in this paper and some modifications are discussed upon the analyses of the limitation of traditional Foucault apparatus. A paraboloidal mirror was fabricated and tested by the modified Foucault apparatus whose effect has been proved to be great. The methods of controlling mid-frequency error are described in the other paper at this conference- "Multi-mode combine manufacturing technology for large aperture aspheric mirrors"1.
