Abstract

We make a novel telescope design using a pair of Alvarez lenses. Previous examples using these types of lenses were single elements used just to provide a change in power. Consequently, the location of the object and/or image plane must move. In this effort, we combine two elements to form a telescope. In this manner, we can fix the location of the object and image plane and simply change magnification. We describe the shapes of the Alvarez lenses used, as well as the advantages, the disadvantages, and the differences between a telescope using Alvarez lenses and a traditional telescope.
