Author Affiliations +
Abstract
Optical performance results are reported for four different molded-glass lenses. All four lenses are intended for use as focus objectives in optical memory applications, including Compact Disc, Laser Disc, and optical storage pickups. All lenses have measured performance below 0.04 waves RMS on-axis at 0.780 micron. The lenses differ in the different performance features they emphasize. These features include excellent off-axis performance, longer working distance, a finite conjugate, and a higher numerical aperture.
