GRIN lenses represent an interesting alternative to conventional spherical lenses since the lens performance depends on a continuous change of the refractive index within the lens material. This paper using of the high-index-of-refraction lanthanum crown glass (SLS-1.0) which helps to reduce spherical aberration the design and analysis the gradient – index lenses by using Zemax software that we can see the changing in refractive index. wave length extends from (0.500 to 0.600) μm and diffraction limited over a large field of angles with F/#2.5 that have been studied in this research .This paperdeals how to design and analysis work and how to take advantage of gradient index image applications,which helps to reduce the modulation of the refractive-index profile.
