Abstract
The two types of diffractive optical elements capable of compensating chromatic aberration in MO data storage optics have been developed. One is a diffractive element that has little optical power, and is used in cooperation with an aspherical objective lens separated from each other. The other is an aspherical singlet with a diffractive grating on its surface. Both have a diffraction efficiency of 100% for the first order diffraction.
