摘要：

In this paper, a lens system is presented, which requires just little space and has a high degree of flexibility in terms of the achievable focal length range. The well-known principle of the Alvarez lens has been newly taken up and enhanced. As a result, it is even possible to achieve a diffraction-limited imaging quality. However, manufacturing such non-rotational symmetric surfaces has many challenges to overcome, which should be discussed. Furthermore, valuable results of the manufacturing process of these freeform surfaces are presented.
