Zemax OpticStudio V16 SP2 New tools tackle stray light and simulate more photoluminescent materials, plus mobility and usability improvements increase ease of use New stray light analysis tools help identify and block unwanted rays in optical systems and streamline stray light analysis to deliver accurate, consistent results faster. Optical engineers working on biomedical, automotive lighting, and other applications that use phosphors and fluorescent materials can now model a wider range of these materials. Usability improvements include faster rendering of analysis windows, and faster results in Layout plots and Shaded Model plots when modifying designs. Plus, you can now transfer your soft key license from one computer to another in two easy steps. This release includes the new Bernhard Halle Lens Catalog, new Nikon Material Catalog, and updated catalogs from NHG, Ohara, Zeon, and Hoya. OpticStudio 16.5's new stray light analysis tools help identify and block unwanted rays in optical systems and streamline non-sequential stray light analysis to deliver accurate, consistent results faster. New capabilities include: Measure the impact of mechanical mounts or the effects of stray light with the new Non-sequential geometric MTF calculation Isolate critical data quickly and specify the quantity of rays to investigate in Ray Database filesby by using new ZRD Filter strings Quickly display stray light paths in the Layout and Shaded Model system viewers by using new Filter strings to limit the number of rays OpticStudio 16.5 includes several usability improvements, so you can: Improve data visualization through faster rendering of analysis windows Get faster results in Layout plots and Shaded Model plots when modifying designs Easily analyze complex diffraction-limited systems accurately with a new manual control of the phase reference for all Huygens calculations Transfer your soft key license from one computer to another in two easy steps Use the new Bernhard Halle Lens Catalog, new Nikon Material Catalog, and updated catalogs from NHG, Ohara, Zeon, and Hoya
