|Format||Member Price||Non-Member Price|
The paper is intended to familiarize optical designers and systems engineers with the versatility of zoom lenses which operate in the thermal infrared waveband and especially the 8-13 micrometer band. Important system considerations and their effect on the mechanical, electronic, and in particular, the optical aspects of zoom lens design are highlighted. An example of a general purpose, modular zoom lens is described and a brief performance assessment is given.
