High accuracy is required in surface testing of 90nm nodal point lithography projecting lens. By comparing various aspheric surface testing methods
the structure layout of the compensator is a meniscus positive lens combined with a Plano-convex positive lens. The design results indicate that: primary and high order aberrations are balanced well
we adopt Offner null compensator to test the aspheric surface in the point diffraction interferometer at last. In this paper
MTF exceeds diffraction limit
an Offner compensator is presented on the base of the third order aberration theory to test concave aspheric surface
root-mean-square (RMS) of wave front error /167. The F-number of the system can achieve F/1.64. By the analysis of the process of aspheric surface testing with the designed system
the optical construction parameters of which is determined by introducing equal-quantities spherical aberration to compensate all orders of aspheric coefficients. The field of view of the system is 0.02
a loosen distribution of the tolerance was presented based on the accuracy of measuring apparatus. 2009 SPIE.

Corrective force solving is a critical technology of the active optics. A method to solve active optics corrective force is introduced
which is based on Householder transform of Zernike polynomial wave front fitting
this method is different from the traditional least square method and Gram-Schmid orthogonal method
because it does not bring ill-conditioned polynomial without constructing normal equation
so it can avoid calculation error
wave front fitting is precision. Based on the coefficient of the Zernike polynomial and the response function of the each actuator
the stiffness matrix of the primary mirror is built
and then adopting the damp least square method to calculate corrective force. Based on this method
cp400m test mirror is simulated many times
the calculation result approve: if the Householder transform is adopted
wave front fitting is precision
the result is stabilization and corrective effectiveness is better.
