Sharpen your optical filter knowledge with our 12-part lecture series on filters. Presented by Turan Erdogan, PhD, these lectures were a part of a day-long group presentation. Dr. Erdogan is a former associate professor from the University of Rochester, Optics Department.
The PowerPoint slides for each presentation are also available from the original lecture. Some of the files are larger and may take a few moments to completely download.
