Abstract:
A method and corresponding optical device to correct spherical aberration in an optical path caused by an electrically tunable lens (ETL) within the optical path. The method includes placing within the optical path and in working relationship with the ETL an aspherical correction lens dimensioned and configured to reduce spherical aberration in a light beam exiting the ETL.
