06049430 is referenced by 15 patents and cites 2 patents.

A composite micro-lens for use in an optical or magneto-optical information storage system, made up of one or more lens elements which, when coupled in assembly, provide a desired numerical aperture. The design may provide, if necessary, a photo resist lens, a shaped ball lens, or one or more contoured surfaces within the composite construction to correct for aberrations. The composite lens designed in this manner allowing for the use of wafer-level assembly processes to provide high volume production capabilities. It is further intended that this micro-lens design support integration in an optical or magneto-optical head design.
