Popis:	A global optimization process is developed for designing an objective lens for multiple-configuration applications. As a demonstration, it is shown that diffraction-limit performance can be achieved for a pickup head used for both compact disks (wavelength 780 nm) and digital versatile disks (wavelength range 635 to 650 nm) with different working distances and focal lengths, at a numerical aperture of 0.6.
