Paper Abstract

The design of a diffraction-limited aspheric lens for optical disc systems is discussed (f=4.5 mm, NA=0.45, wavefront distortion less than 0.045 wavelength rms). The design for mass-production is a mono-aspheric lens consisting of a piano-convex glass body with a correction layer of ultraviolet-curing lacquer. The optical quality of the lens is measured with a phase-stepped interferometer. A few details of the interferometer are given and the aberrations of the mass-pruduced lenses are discussed.
