My Guiding Principles

Coming soon.

Dr. Holger Claus is the Vice President of Technology at Ushio America Inc.. He holds a masters degree and PhD in lighting. Throughout his career he has developed and produced various kind of light sources, like fluorescent lamps, UV lamps, short arc Xenon, laser driven Xenon and super high pressure Mercury lamps, LED and laser products, and excimer lamps. He has extensive knowledge and experience of application related questions of these lamps including drivers, measurements and regulatory questions. He is leading the technical, scientific and regulatory efforts of Ushio America Inc. to introduce 222nm lamps into the scientific community and the market. He has written multiple scientific papers and white papers related to the application of 222nm Filtered Far-UVC technology. He is a member of IUVA, IES, CIE and is participating in various standard committees related to germicidal UV.
