PTAI216 色像差意味着不同波长的光聚焦在不同的点。由于玻璃的色散决定了其在不同波长下的折射能力,因此可以通过设计包含凹凸透镜(使用具有不同色散的玻璃制成)的成像镜头来去除色像差。图6描述了该情况,将单透镜与消色差双合透镜进行了对比。这种设计的一个缺点是,它增加了镜头所需的元件数量。
要减少像差,通常需要使用折射率较低(色散系数较高)的镜头。如前文所述,需要折射率更高的镜头来更正球面和像散色差;如果需要更正镜头的球面、像散和色像差,则需要额外镜头元件。此外,理想的颜色校正玻璃所具备的属性通常会令其更加昂贵,并且难以生产。如果可能,请使用单色光尽可能减少色像差,这样可以显著节约成本并降低复杂性。
