Abstract
In this paper,a simple and clear index expression of planar microlenses is obtained through actually measuring the index distribution and mathematically simulating.The index function is the sum of decomposed functions of radial distance and axial distance.By using the basical optical equation,the ray trace is calculated and these equations describing the imaging property of planar microlenses are derived.In this paper,the numerical aperture and the effect of the swelled structure are also discussed.
