REDMOND, Washington, Oct. 29, 2014 — Radiant Zemax has sold its Zemax optical design software business unit to Arlington Capital Partners. The sale price was not disclosed. Vice President Dr. Mark Nicholson has been named CEO of the stand-alone Zemax business. The Radiant side of the business will continue to operate as Radiant Zemax and focus on its integrated imaging systems to measure light and color in flat-panel displays, illuminated keyboards, LEDs and other light sources. Radiant Imaging and Zemax Development Corp. merged in 2011 under the ownership of Evergreen Pacific Partners. The merger enabled Zemax to invest heavily in its flagship product, OpticStudio.
