Paper Abstract

A diffraction-limited bi-aspherical readout lens for the digital audio disc system has been designed and developed based on a high-precision lens replication process using UV-polvmerizable coatings. This single element read-out lens consists of a hall-shaped quartz substrate with two aspherical replicated coating surfaces. The design of the bi-aspherical lens is presented and its production described. The optical performance of the lenses proved to be reasonable with an rms-OPD of 0.055 λ, the primary lens aberration being spherical aberration.
