Abstract
A method of generating a target surface {tilde over (S)}() of an optical lens for the manufacture of the optical lens according to optical lens parameters, the method comprising: providing a set of L first surface difference data E(λ) each first surface difference data E(λ) corresponding to the surface difference between a pre-calculated surface S(α) (j=1, . . . , L) and an initial surface S(j=1, . . . , L), from which the target surface will be generated, according to the expression:(λ)=(α)−(j=1, . . . , L)where λ(j=1, . . . , L) correspond to the optical lens parameters of the pre-calculated optical lenses; providing a set of second surface difference data {tilde over (E)}() corresponding to the surface difference between the target optical surface {tilde over (S)}() and the initial surface Sby linear interpolation of the first surface difference data E(λ) according to the expression: where wrepresents an interpolation coefficient; and; determining the target surface {tilde over (S)}() by combining the second surface difference data {tilde over (E)}() and the initial surface Saccording to the expression: {tilde over (S)}()={tilde over (E)}()+S.
