Optical design of Galilean telescopes using hybrid elements (refractive-diffractive) for people with low vision

摘要

In this work we propose the optical design of Galilean telescopes for low vision people using hybrid optical components. By use of these new optical components we have obtained compact and lightweight optical systems without detriment of the optical quality of the images. We present the optical design of telescopes for three different magnifications, as well as the evaluation of the image quality using the eye model proposed by Bruce H. Walker.
