Freeform Optics - Will it be in your future?
The Institute of Optics, University of Rochester
ABSTRACT Slow-servo diamond turning has revolutionized what is possible in optical fabrication. As a result, optical design provides new horizons where freeform surfaces may offer new degrees of freedom. In this talk we will provide a brief history of the emergence of freeform optics and point to a growing customer base. We will then discuss recent advances in surface shape descriptions for freeform optics from phi-polynomials to multi-centric radial basis functions. Finally, we will show how freeform surfaces may provide in one case study a factor of 10 in f-number and a factor of 10 in field area. Insight into the correction of aberrations will be provided and a metrology approach to testing freeform surfaces will be discussed.
