title: System design process for refractive simultaneous short and long wave infrared imaging.
abstract: The future of optical design is multispectral imaging. Advancements in detector technology have led to the challenge of imaging over both short wave infrared and long wave infrared spectrums. This paper discusses the technical hurdles associated with designing a refractor to image over both of these spectrums, such as minimizing chromatic focal shift while maximizing contrast. The design process is outlined on an eight element F/1, 23° full field of view solution. Optomechanical design forms are evaluated by analyzing possible stresses and tolerance errors. Antireflection coating designs are discussed to complete the full system. This entire design process is highlighted as a feasibility study for the future of multispectral imaging devices.
