| titleOfInvention | Optical aberration correction device |
| abstract | An optical aberration corrector including an electrochromic element capable of correcting aberrations such as coma and spherical aberration without generating polarized light and without continuously applying a voltage. A laser beam (1j) emitted from a laser light source (1a) is disposed on an optical path of an optical system that focuses the laser beam (1j) on a recording medium (1e) via an objective lens (1d). An optical aberration correction device for correcting aberration, comprising an electrochromic element 1c disposed between a laser light source 1a and a recording medium 1e, wherein the electrochromic element 1 has an electrochromic layer and reads recorded information. The electrochromic device has a structure in which the refractive index of the electrochromic layer is changed by the voltage applied to the device before and the change in the refractive index is maintained even after the application of the voltage is released.
