ABSTRACT:
An optical system comprising a radial type gradient index lens component which has a refractive index distribution in a radial direction from an optical axis in a medium thereof, and configured to correct chromatic aberration sufficiently favorably by selecting a difference between a partial dispersion ratio on the optical axis and that on an effective diameter when a gradient of the distribution of the radial type gradient index lens component is different dependently on wavelengths.
