Abstract:

Subject of the study. Simple in design infrared objectives that include, along with homogeneous lenses, a single radial gradient-index lens or a gradient-index lens and a diffractive optical element together. Purpose of the study. Development of a methodology for the layout and calculation of simpledesign lenses for the infrared spectrum with hybrid element base. The research method. Theoretical analysis, computer modeling and optimization using the ZEMAX optical design program. The main results. The presented methodology covers all stages of the layout and calculation of the lens. It includes selection of optical materials for all its elements, recommendations on using the optical scheme obtained from the condition of its achromatization, apochromatization or superchromatization as the initial one for subsequent optimization in the ZEMAX optical design program, as well as on combining a gradient lens with a diffractive optical element in the objective scheme and calculating a super-high-aperture dual-range gradient-diffractive objective. The efficiency of both the combined use of gradient and diffractive elements and the presented technique is demonstrated using the example of calculating an ultra-high-aperture gradient-diffractive objective. Practical significance. The results of this study open up the possibility of creating simple-in-design high-aperture dual-band infrared objectives based on coaxially laminated radial gradient-index lenses.

Keywords:
