Micro objective lens with NA 0.65 for the blue-light small-form-factor optical pickup head.

A micro objective lens with the numerical aperture (NA) of 0.65 and clear aperture of 1.1mm was designed, fabricated, and tested for the proposed blue-light small-form-factor optical pickup head system. It adopted the finite optical conjugation and could be produced by using the glass molding technique. The experimental results verify the optical performance near the diffraction-limited focus spot for the applications of high-density portable optical storage systems.
