Abstract
The present invention provides a general system and method for designing arbitrary lens systems with reduced chromatic aberration without the reliance on rigorous trial and error methods and/or approximations. The system and method selects optical materials for a color corrected optical system by generating both axial color terms and lateral color terms for a predetermined lens system. From the generated color terms, a plurality of glass terms are calculated from a plurality or linear algebraic formulas generated by a multiplication of two matrices using the generated axial and lateral color terms as coefficient values of one of the matrices or other computational method. From the calculations, the particular optical materials and the predetermined lens design for a color corrected optical system are identified. This information can be used to facilitate the manufacturing of a lens system. The present invention can also take into account the use of diffractive optical elements.
