Abstract

A design is presented for an objective lens for the Compact Disc system. The objective is a single-element glass lens with one aspheric replicated surface and one flat surface. The temperature behavior of the lens is studied and compared with that of a plastic lens. The aspheric surface is manufactured by replication and is suitable for high-quality mass production.

Wave front aberration of the lens of Fig. 1 for an off-axis pencil (80 μm off the axis of the image field). The solid lines give the aberration with respect to the paraxial image point, the dashed lines with respect to the best axial and transverse focus of the wave front. Y is the field position in millimeters and Z is the amount of defocusing in millimeters, n = 1.55.
