From deep learning to high-end optical design, the 2019 webinar program provided photonics fanatics with 35 opportunities to learn about new developments in optics and photonics, and to refresh their knowledge of established technologies. Webinar presenters from industry and academia shared their expertise in optical design, imaging and microscopy, machine vision, laser applications, and more. Below is a partial list of webinars hosted by Photonics Media throughout the year. We extend a huge thank you to our presenters for generously sharing their time, knowledge, and experience to educate and inform us about what’s going on in these constantly changing fields. We would also like to thank subscribers for their support and suggestions. If you are interested in seeing our complete webinar listings, past and present, visit www.photonics.com/webinars. This link will also give you on-demand access to Photonics Media webinars for viewing at your convenience. We are looking forward to the advancements that 2020 will surely bring, and to developing a webinar schedule for the new year that will support both the breadth and the depth of our industry. January — “SiPM and SPAD: Emerging Applications for Single-Photon Detection,” presented by Slawomir Piatek and Hamamatsu Corp. Piatek provides an overview of sensors for low-light-level applications and the many ways they can be used. February — “Emergence of Freeform Optics in Imaging Systems: A Leap Forward,” presented by Jannick Rolland and Aaron Bauer from the University of Rochester. Rolland and Bauer discuss the latest design methods and fabrication techniques for freeform optics. March — “A Bird’s-Eye View of AR Coatings, from Concept Through Production,” with optical design and production trainer and consultant Ron Willey, who discusses concepts, design principles, and equipment used. April — “Quantum Dots Are Making Displays Brighter and Photomedicine Better,” presented by Peter Palomaki, the owner and chief scientist at Palomaki Consulting and the chief technology officer and CEO of QLEDCures. Palomaki discusses engineering advancements in QDs, strategies for implementing them in displays, and applications outside of the display industry. May — “Spectroscopic OCT: Seeing Under the Skin with Depth-Resolved Spectroscopy,” with Adam Wax of Duke University. Wax discusses SOCT for analyzing structural as well as spectroscopic information and its application for treatment of skin injuries. June — “VCSELs and Their Role in the Evolution of Photonic Systems,” with Axel Scherer of the California Institute of Technology, who pioneered the development of the first monolithic vertical cavity lasers (VCSELs). Scherer invites surprise guest Jack Jewell, who with Scherer created the first prototypes for VCSELs, to co-present. July — “Keys to Success with Vision-Guided Robotics,” presented by vision expert David Dechow, who provides an overview of cutting-edge VGR applications for machine vision systems, and tips on integrating software, cameras, and robots into your VGR application. August — “High-End Asphere Design for Manufacturability,” with the asphere experts at Edmund Optics, Amy Frantz and Oleg Leonov. They discuss the benefits of designing with aspheres and how to design for manufacturability. September — “Hands-On Digital Light: Spectral Design Tools for Human-Centric Lighting,” a hands-on primer presented by Josep Carreras and Aleix Llenas of LEDMOTIVE and the Catalonia Institute for Energy Research. October — “OCT and Ophthalmology in the Age of Artificial Intelligence,” with Nishant Mohan, vice president at Wasatch Photonics. Mohan gives an overview of how AI is transforming the field of medical imaging. November — “High-Yield Optimization: Streamlining the Path to More Easily Manufacturable Optical Designs,” with Zemax founder Kenneth Moore. He discusses a new approach to creating manufacturable, high-yield, low-cost optical designs. December — “Vision Systems for Deep Learning,” with Basler’s medical product marketing manager, Felix Chemnitz. He discusses three types of vision systems that can be used to deploy a trained neural network in the medical and life sciences fields today.
