若條件(7)Vd1的值大於20，則使第一透鏡L11的修正色差能力下降。因此，Vd1的值至少須小於20，所以最佳效果範圍為17<Vd1<20，符合該範圍則具有最佳消色差條件。 If the condition (7) the value of Vd 1 is greater than 20, the ability to correct chromatic aberration of the first lens L11 is reduced. Therefore, the value of Vd 1 must be at least less than 20, so the best effect range is 17<Vd 1 <20, and if this range is met, there is the best achromatic condition.
