Paper Abstract

The design and expected performance of an all-glass, high-NA, collimator/objective lens pair are described. The numerical apertures are: 0.55 (objective) and 0.40 (collimator). Both lenses are biaspheric and both are designed to perform over relatively broad wavelength and temperature ranges. The as-fabricated, on-axis wavefront error of both lenses is expected to be less than 0.04 waves (RMS, 765-845 nanometers). This is one of the first such glass matched pairs to be designed for use with laser diodes in compact-disc, video-disc and optical-memory applications.
