Abstract
This paper introduced a new type of tenses with approximate bite lecentricity for photolithography.It has the quasi-diffraction Limited image quality in the range of large field size and keeps fine overlay accuracy as well.The corrections of sagittal aberrations and higher order aberrations are considered in the optical design. Finaty, the MTF of two results, with NAO•2, magnification x, field diameter 140mm, and NAO•28, magnification lOX, field diameter 140mm, were given.
