Abstract
Aspheric lenses of conventional optical glasses have been molded. A 16 mm diameter photographic lens with aspheric figure error of 0.6)1m, accuracy error of 0.04 μm, decenter of 75" and surface roughness of 200 Å Rmax has been obtained. For an aspheric pickup lens in a compact disc system, a wave-front aberration within 0.04 μm rms has been obtained.
