Lens systems (8, 18, 28, 38, 48, 58) with first and second rigid lens elements and a liquid lens element therebetween are provided. The first and second rigid lens elements (10, 11; 20, 21; 30, 31; 40, 41; 50, 51; 60, 61) and the liquid lens elements (16, 26, 36, 46, 56, 66) co-act with each other to cause the lens system to have substantially diffraction limited performance over a continuous ultraviolet wavelength band, wherein the first and second rigid lens elements and the liquid lens element are configured and positioned with respect to each other according to a selection of particular designs and design forms.
