Abstract

A novel design and production of hybrid optical surface used in single BD/CBHD compatible objective lens is presented. The hybrid surface contains both diffractive and aspherical optical structures which are generated by single point diamond turning of optical grade plastics. From optical path analysis, the aberration of the focal spot generated by the objective lens is evaluated. The results are used to revise the aspherical coefficient of the hybrid surface so as to compensate for the optical deviation caused by stringent requirement on the radius and angle of the diamond tools used in diamond turning to produce an optical surface with nanometric accuracy.
