Abstract
We presented the meridional ray tracing method for a planar microlens with 3-D distributed index and aspheric boundaries, and estimated its N.A. and spherical aberration1),2). But the off-axial characteristics of this lens has not been estimated. In this paper, we aim to estimate a planar microlens by more general ray tracing which includes the calculation of path length.
