| 摘 要： | Since the complete correction of all five monochromatic Seidel aberrations for a singlet lens with random shape or a two-thin-lens system is unprocurable merely by using the conventional positive-index materials both in theory and practice, this paper proposes that when one or both of the two lenses is/are made from negative-index materials, an imaging system composed of a pair of spherical thin lenses is possible to form a real image, in air, free from all five monochromatic Seidel aberrations. The calculated numerical solutions to the structural parameters of such lens systems possessing superior performance are provided and examples of them are illustrated for the given combinations of the two lenses＇ refractive indices, including an ultimately-remote imaging system.

| Abstract: | Since the complete correction of all five monochromatic Seidel
aberrations for a singlet lens with random shape or a two-thin-lens
system is unprocurable merely by using the conventional
positive-index materials both in theory and practice, this paper
proposes that when one or both of the two lenses is/are made from
negative-index materials, an imaging system composed of a pair of
spherical thin lenses is possible to form a real image, in air, free
from all five monochromatic Seidel aberrations. The calculated
numerical solutions to the structural parameters of such lens
systems possessing superior performance are provided and examples of
them are illustrated for the given combinations of the two lenses'
refractive indices, including an ultimately-remote imaging system. |
