ABSTRACT:
Lens systems (68, 78, 88, 98, 108, 118) with first and second rigid lens elements (70,71;80,81;90,91;100,101;110,111;120,121) and a liquid lens element (76, 86, 96, 106, 116, 126) therebetween are provided. The first and second rigid lens elements and the liquid lens elements co-act with each other to cause the lens system to have substantially diffraction limited performance over a continuous infrared 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.
