Title: Method of designing compensation lens
Inventor: UEDA MASAHIRO
IPC: H01J9/227
Filed: 1994-01-31
Abstract: PURPOSE:To design a compensation lens simply in a short time by setting lens curved surface functions separately for plural kinds of landing patterns, and giving a coefficient to each lens curved surface function. CONSTITUTION:Lens curved surface functions about the contirluous lens curved surface to correct the dislocation of the landing are set separately for plural kinds of landing patterns P1-Pn in face panels 2. The landing vectors at the landing patterns P1-Pn which can be corrected with the continuous lens curved surface of a correcting lens are made L1-Ln, and the lens curved surface functions to correct the landing patterns P1-Pn are made F1-Fn. Next, the landing vector L at the desired landing pattern p is set not only by giving coefficients beta1-betan to the landing vectors L1-Ln at the reference landing patterns P1-Pn but by their similarity. The lens curved surface function N is calculated, making use of the selected coefficient. Hereby, an optimum lens curved surface function can be gotten.
