| abstract | An objective lens includes a first optical path difference providing structure in which a first basic structure and a second basic structure are overlapped together, and a second optical path difference providing structure in which a third basic structure, a fourth basic structure, and a fifth basic structure are overlapped together. The first and third basic structures emit diffracted light fluxes with the same diffraction order having the maximum light amount. The second and fourth basic structures emit diffracted light fluxes with the same diffraction order having the maximum light amount. The fifth basic structure emits 0th-order diffracted light fluxes with the maximum light amount, for the first light flux, emits 0th-order diffracted light fluxes with the maximum light amount, for the second light flux, and emits Gth-order diffracted light fluxes with the maximum light amount, for the third light flux, where G is an integer excluding zero. |
