Imaging with thick lenses using ABCD matrices and first-order material dispersion

ABCD matrices for a thick lens based on first-order frequency-dependent material dispersion of dielectric permittivity are derived using standard paraxial theory and spherical surfaces. The analysis and results are compared with the non-dispersive problem and used to ascertain imaging behavior for a gray scale 2D object. The possibility of introducing chirality and negative index in the lens material is also discussed.
