Stray Light Short Course Course Overview Photon Engineering’s stray light short course is an intensive 3-day instruction on the language, science, theory, techniques, and calculations involved in all aspects of stray light. Prerequisites Attendees should have a rudimentary knowledge of optical design and radiometry. No knowledge of stray light topics is assumed; the course starts with very basic radiometric concepts and develops the relevant language, theory and techniques. This short course is not taught with a particular software package in mind; the techniques and discussion topics are generic to the field of stray light. Consequently engineers using any of the commercial software packages will benefit from attending this short course. Instructor The instructor is Mr. Richard N. Pfisterer, president of Photon Engineering. Mr. Pfisterer has over 30 years experience in the areas of stray light analysis, algorithm and software development, hardware testing, contamination control, industry practices, and optical design. He has direct experience working with virtually all commercial (and several proprietary) stray light software. The material presented during the course reflects his very broad knowledge of the field.
