Abstract

The aberrations are introduced by a hemisphere solid immersion lens (SIL) with a thickness error or a lateral eccentricity in the SIL optical data-storage system. Numerical computation about these aberrations is presented. We have investigated the influence of these aberrations on the focus spot size, signal intensity, and signal contrast. The simulation results show that a tolerance of the SIL is about ± 20μm in the thickness or in lateral eccentricity.
