Correction of Secondary Spectrum Based on Normal Dispersion Glasses
基于正常色散玻璃二级光谱的校正

The theory for the design of optical systems corrected of secondary spectrum by using normal glasses is presented. The algorithm for the evaluation of secondary spectrum contribution on each surface is developed and applied to the design of optical systems. Two design examples are given.In both design examples the secondary spectrum is well corrected by using standard glasses only.
