Several approaches to design of lens with minimized curvature of the image in the field of second and third aberration orders are discussed. The approaches under consideration are based on the use of inhomogeneous optical material with radial gradient of the refractive index. Application of such lenses is reported to allow for simplicity and decrease in overall dimensions of optical system components.
Рассмотрены подходы к расчету линзы с минимизированной кривизной изображения в области аберраций третьего и высших порядков на основе применения неоднородной оптической среды с радиальным градиентом показателя преломления. Такая линза может быть использована с целью конструктивного упрощения компонента оптической системы для минимизации его габаритов.
