Paper Abstract

It is well known that the decentering in the lens manufacturing process decreases MTF-value of lenses. A computer simulation method is developed which estimates loss of the yield in the manufacturing process caused by decentering. The method is useful to evaluate the productability of the designed lenses for massproduction, and, moreover, will give proper suggestions to improve the yield without changing lens element. This method also enables us to select proper lens type. The method to improve the yield is discussed in detail referring several examples.
