Summary:PROBLEM TO BE SOLVED: To provide a chromatic aberration expansion optical system for easily generating a desired axial chromatic aberration at low cost while substantially maintaining optical performance except the axial chromatic aberration of a basic optical system when mounted to the basic optical system. SOLUTION: The chromatic aberration expansion optical system 200 is constructed to have a positive lens component G1 and a negative lens component G2. The chromatic aberration expansion optical system 200 is added to the basic optical system 100 after aberration correction to expand only the axial chromatic aberration while substantially maintaining the optical performance except the axial chromatic aberration of the basic optical system 100.
