Расчет центрированного зеркального объектива с эксцентрично расположенным полем изображения

Reflecting objectives with eccentrically located image field are widely used in optoelectronic equipment for the remote Earth sensing and are prospective for using in hyperspectral equipment, which requires high image quality in a wide spectral range and large angular field. We consider one of the most common and simple form of the reflecting objective with eccentrically located field image a three-mirror lens that can be applied both independently, and as a basis (catadicptric) lens when creating mirror-lens optical systems. Consequently, we offer the methods for calculating the aberration and the analysis of the effectiveness of aspheric surfaces on the lens. As a result, we give an example of calculating the objective using the analytical dependencies
