Abstract
Provided is a method for designing an image pickup lens which is low cost and applicable to reflow process. The method includes a step of designing the image pickup lens including a lens formed of energy curable resin, on the assumption that the energy curable resin is homogeneous; a step of obtaining an image pickup lens by manufacturing each lens forming the image pickup lens, based on the design; a step of evaluating lens performance of the obtained image pickup lens; a step of designing the image pickup lens again by changing surface shape of at least one surface and/or lens-surface distance in at least one place in the image pickup lens, based on the lens performance obtained by an simulation in the designing step and the lens performance of the image pickup lens obtained in the evaluating step.
