Abstract
An infrared lens system for projecting an image from object space onto a flat image plane, the lens system being corrected over the spectral region of 3.3 to 4.2 microns and having a selectable narrow field of view comprising: an objective lens system having a plurality of lens elements formed of material optically transparent over the spectral region of 3.3 to 4.2 microns, the plurality of lens elements being coaxially aligned and adapted to receive light from object space and to form an image on the flat image plane, a selectable afocal telescope, the selectable afocal telescope being in select field of view determining relation with the objective lens system, whereby upon selection, the selectable afocal telescope cooperates with the objective lens system to provide a narrow field of view.
