摘要：
There is disclosed an objective lens (16),for use with optically readable disks of differing cover layer thicknesses, wich objective lens (16) comprises a variable lens (1) formed by the interface between two immiscible fluids (A, B), which variable lens (1) can be in one of at least two discrete states and whereby the focus point of the objective lens (16) varies between the two states of the variable lens (1).
