Abstract
People with visual weakness, besides the typical refraction problems as myopia (shortsightedness), lose much of the light that enters to their eyes because their retina has many useless cones. For this reason the traditional ophthalmic lenses cannot solve the problem of these people, therefore, we are required of optical systems that collect a big quantity of light, we also need these systems to be of small dimensions and lightweight so they can be used for a long time. In this work we propose the optical design of telescopes using hybrid components, using this new optical components we have obtained compact and lightweight optical systems without decreasing the optical quality of the images. We present the optical design of telescopes for three different magnifications, as well as the analysis of the quality of their images.
