Freeform Optical Surfaces
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 I will provide a brief history of the emergence of freeform optics and point to a growing customer base. I 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 field area. Insight into the correction of aberrations will be provided and two metrology approaches to testing freeform surfaces will be discussed.

General Information on NES/OSA Meetings
Cancellations and No-shows:
If the meeting must be canceled for any reason, we will try to call you at the phone number you leave with your reservation. Official notice of cancellation will be on our answering machine.
We have to pay for the dinners reserved as of the Tuesday before the meeting, so no-shows eat into our cash reserve. If you will not be able to attend, please let us know as early as possible. Otherwise, no-shows will be billed.
NOTE: The extra $5.00 of the non-member dinner fee can be used toward membership dues if the nonmember joins and pays dues for the current year at the meeting.
