Abstract:A technique for providing apochromatic correction in the wavelength range from 3 to 12 μm, which makes it possible to substantiate the choice of materials and optical powers in an optical system with components separated by an air gap, is discussed. Using numerical methods, it is shown that the solutions found can serve as starting systems for the development of dual-band lenses that provide a stable position of the image plane in the ranges of 3-5 and 8-12 μm, coupled with uncooled dual-band infrared detector… Show more
