B. H. W. Hendriks, M. A. J. van As and A. A. M. van Alem

(Received February 3, 2005; accepted May 28, 2005; published September 8, 2005)

The design, manufacturing and testing of a miniaturised singlet plastic injection molded high-numerical aperture objective is discussed. To reduce the temperature dependence a non-periodic phase structure is incorporated in the aspherical surface of the lens. Readout experiment with this objective in an optical drive is performed.
