A review paper has been previously published on infrared zoom lenses in the 1980s1. Subsequently, a paper was published on infrared zoom lenses in the 1990s2. It is timely to prepare a paper on developments and trends in infrared zoom lenses in the decade since the year 2000. These trends include the shift from scanning systems to CCD and focal plane arrays, dual band systems, advances in simulators for target detection, high zoom magnification ratio, reflective zoom systems, and developments and trends in infrared materials and detectors. Examples are presented to illustrate each of these trends. These examples are predominently mechanically compensated zoom lenses, although one optically compensated zoom lens is also included.
