Photon Engineering

Illumination system designer Steve Mulder has joined Photon Engineering on May 21, 2012. In his role as Senior Illumination Engineer, Steve brings a broad range of illumination design experience to the Photon Engineering design team, especially in automotive and signal lighting, light guides, and reflector optics applications. He has worked in the optical design field for over 25 years, including modeling, fabrication, and system development. He also brings expertise in software development for illumination design and analysis. Steve has joined the consulting group at Photon Engineering, so he is ready to assist you in the design and analysis of your illumination systems.

Dr. Koshel is a leader and innovator in the optical engineering community, specifically in the fields of illumination and non-imaging optics.  In addition to his position as the VP of Consulting at Photon Engineering, LLC., Dr. Koshel is also an adjunct professor at the University of Arizona’s Optical Sciences Center where he teaches courses on Illumination Engineering and Radiometry, Sources and Detectors.  His responsibilities also extend to leadership positions in professional societies, including the OSA, SPIE and IESNA.  His extensive authorship reflects his interest in both historical and current developments in optical engineering as well has his dedication to mentoring the next generation of professional engineers.
