Paper Abstract

Hybrid refractive-diffractive elements have the potential to provide chromatic correction with less than half the material content of a conventional doublet. It is shown that the performance of a general hybrid meniscus element can exceed that of the equivalent doublet. Their design and potential advantages are illustrated to good effect in a Petzval objective example. 1.
