Abstract:
1. A method for manufacturing an optical system comprising the steps of: i. selecting at least one criterion from among the groups consisting of: ii. for each criterion selected in step i.), defining: iii. selecting a starting optical system and defining a working optical system to be equal to the starting optical system, wherein the starting optical system and the working optical system are each defined by coefficients of equations of its surfaces, an index of glasses thereof, and positions of each surface relative to each other, and wherein each optical system comprises at least two optical surfaces of a same lens; iv. evaluating for the working optical system and for each criterion selected in step i.): v. modifying at least coefficients of equations of the at least two optical surfaces of the working optical system to minimize a cost function considering target values and criterion values by repeating step iv.) until a stop criterion is satisfied, wherein the at least two optical surfaces comprise at least a front and a back surface; vi. calculating by optimization the optical system; and vii. surface machining at least one optical surface in accordance with said calculated optical system.
