Paper Abstract

The demands on optical metrology such as Fizeau interferometers increase steadily. Typically, a Fizeau lens design consists exclusively of several spheres. Since there is a growing need for larger measuring ranges as well as higher NA of Fizeau lenses, classical spherical Fizeau lenses increasingly reaching their limits. In this paper, a prototype of an innovative transmission sphere comprising aspheric surfaces is introduced and some results and new findings of the manufacturing and testing are presented.
