By Thomas Efsen, managing director, Efsen UV & EB Technology An integrating sphere uses multiple diffuse reflections of light incident on the sphere inner surface to homogenize the light over the entire surface (Figure 1). This results in uniform irradiance at all points on the interior surfaces of the integrating sphere. This has been applied to UV curing by … [Read more...] about Three-Dimensional and Uniform UV Curing Using Integrating Sphere Technology
