Abstract
In this paper, the oxide compositions model (OC model) is established for discussing the chromatic aberrations of gradient refractive index rod lens. The chromatic aberration for Na+/Li+ ion exchanges is discussed based on the OC model and the Huggins–Sun–Davis (HSD) model. Theoretical result indicates that the function value mainly depends on base glass properties and nature of exchanging ion pairs, and hardly depends on the quantity of ion exchanging. Experimental results show that the chromatic aberrations using the OC model have smaller errors than them using the HSD model. The estimating average error between the OC model and the HSD model is −0.0067 for the Na+/Li+ ion exchanges.
