The authors have developed and prototyped an adjustment-free two-component objective lens for a blue laser disk system (numerical aperture = 0.85, disk thickness = 0.1 mm). The lens is designed to be sufficiently tolerant to the relative position, i.e., the decentering, tilt and spacing inaccuracy between the two lenses, and does not require adjustment of the two lenses. We have carried out some experiments and the tolerance of our newly developed objective lens has been experimentally verified.
