【Abstract】 In this article, the contributing factors to gradient index (GRIN) rod lens chromatic aberration are discussed, and according to Fantone model, the principles of selecting ion-exchanging pairs and of determining base glass properties for a low chromatic aberration GRIN rod lens prepared by ion exchanging process are presented visually in the optical glass N d-V map. The analysis shows, using the glass with typical optical properties as the base glass, both Na +/Li + exchanging and K +/Cs + exchanging are suitable for preparing a low chromatic aberration GRIN rod lens, while K +/Tl + exchanging and Na +/Ag + exchanging might produce a GRIN rod lens with much higher chromatic aberration. These principles are instructive in the fabrication of a low chromatic aberration GRIN rod lens.更多还原
