Abstract

A radial gradient index aplanatic singlet pickup objective lens for the compact disk (CD) system has been designed, manufactured, and evaluated. We have realized a piano-convex aplanatic singlet by optimizing the refractive index coefficients of the GRIN medium,lens thickness and one curvature. The GRIN singlet was mounted in a CD player and tests confirmed that the lens meets the system requirements.
