ABSTRACT:
An infrared objective device with optical achromatization and athermalization comprises a front convergent assembly having at least one divergent lens acting as a port and one convergent lens, and a rear divergent assembly comprising at least one divergent lens. These three lenses are chosen so as to be made of three different materials of the type that can be used in the 8 to 12 .mu.m spectral band. They may notably be made, respectively, of germanium, chalcogenide and zinc sulphide.
