LTI Optics Staff Resume - Mark Jongewaard

Profile

Mark served as Vice President, Director of the Optics Division and part owner of Lighting Technologies, Inc. (LTI) until 2006 when LTI was sold to Musco Sports Lighting. Since the sale, Mark has led the formation of LTI Optics (LTIO), which is spinning off from Musco and continuing the optics related business from LTI. This includes the development and sale of Photopia, the most widely used optical design software in the architectural lighting industry in 38 countries around the world, as well as providing optical design services for illumination based (non-imaging) optical systems.

Mark worked for LTI since 1989 and has extensive experience in lighting software development, lighting and optical analysis, illumination optical design and training. The broad experience in lighting analysis and algorithm development has influenced the calculation modules in all of LTI's products including Photopia, Lumen-Micro and Lumen Designer. Through the sales & support of the Photopia software, work on optical design projects and role as training seminar instructor, Mark has maintained close personal relationships with the R&D departments of lighting manufacturers around the world. This position has provided Mark with a unique perspective of the global lighting industry and insights into its major contributors.
