Fluence Spheres

UVC Disinfection | New Lamps, Materials and Fluence Tutorial

UVC disinfection is a popular topic and so we've made many library additions to Photopia 2020.1 for use in that area, including 20 UVC light sources and 7 UV specific materials. We've also created a tutorial that shows you how to compute Fluence in a Photopia project. Fluence is used to quantify the energy incident on particles in a volume and a common metric for UV disinfection.

More Color Materials

We've added 113 reflective materials that have full spectral data. This complements the wide range of color filter transmissive materials we also have in the Library. These materials are the 99 samples from the IES TM-30 CES and the 14 samples from the CIE 13.2 1974 CRI sample set. When combined with a full spectral lamp model, you can predict the color shift of light reflective off these materials.
