Freeform Optics for Imaging: Design Methods
Wed, May 26, 2021 1:00 PM - 2:00 PM EDT
The rise of freeform optics in imaging applications has led to optical systems with increased etendue, more compact volumes, and superior performance. In this presentation, Jannick Rolland, Ph.D., and Aaron Bauer, Ph.D., of the University of Rochester’s Institute of Optics will provide an overview of the methods in which systems utilizing freeform optics have been designed and the steps taken to bridge freeform design to manufacture. Examples of freeform systems from space applications to an application in the movie industry will be discussed. Part 1 of the 2021 Freeform Optics Series.
Freeform Optics for Imaging: Manufacturing Methods
Thu, May 27, 2021 1:00 PM - 2:00 PM EDT
In this talk Matt Davies, Ph.D., of UNC Charlotte, and John Lambropoulos, Ph.D., of the University of Rochester, discuss the current methods employed for manufacturing freeform optics, as well as those methods’ comparative strengths and the limitations. In particular, they examine the need for post-processing (finishing) and its interactions with other manufacturing steps and methods. Part 2 of the 2021 Freeform Optics Series.
Freeform Optics for Imaging: Mid-Spatial Frequency Errors
Wed, Jun 2, 2021 1:00 PM - 2:00 PM EDT
Residual mid-spatial frequency (MSF) surface errors are common byproducts of the computer-controlled sub-aperture manufacturing techniques needed for fabrication of freeform optics. In this presentation, Thomas Suleski, Ph.D., provides an overview of MSF surface error signatures, specification methods, and performance impacts. Part 3 of the 2021 Freeform Optics Series.
