Photon Engineering’s Mastering Stray Light Analysis Short Course is an intensive 3-day instruction on the language, science, theory, techniques, and calculations involved in all aspects of stray light. As a practical course on the theory and calculations involved in stray light analysis, no software programs are used during the class. The topics covered include the radiometry of the BSDF, scatter model definitions, applying and interpreting BSDF functions, scatter model approximations, stray light calculations of PST, contrast/veiling glare, ghost imaging, thermal self emission, and diffraction, effective baffling and beam dumping, and more.
In-person short course (Tucson office, 3-days): Nov 07 – 09, 2022

Instructor
With over 30 years of experience in the areas of stray light analysis, algorithm and software development, optical design and contamination control, instructor Rich Pfisterer is an industry expert. He has direct experience working with virtually all commercial (and several proprietary) stray light software packages. The material presented during the course reflects his very broad knowledge of the field.
