Designing principles for a low chromatic aberration GRIN rod lens
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.
