Abstract. Analysis of refractive index gradient and design of a positive lens providing atypical correction of image field curvature is presented. The results are employed in design of optical schemes of endoscopic type and Pin Hole lenses.
Keywords: lens, radial gradient of the refractive index, image field curvature
