In addition and as an alternative to our stable and high reflectance PTFE material Zenith®, we are offering a cost saving possibility to obtain a solid and diffuse reflectance surface.  Spectraflect® is a paint on the basis of Barium Sulfate which can easily be applied and which shows a reflectance value of 95% in the area of 300nm to 1200nm. This coating is suitable for big integrating spheres, surfaces and bodies, which are not exposed to high temperatures (< 70°C).
