VIAVI Engineered Diffusers can be tailored to spread an input beam according to specific operating and application needs. Light distribution is typically defined by radiant intensity, which measures power per unit solid angle in a given direction. This can be visualized by moving a detector along an arc centered on the diffuser to map illumination in angle space. The technology supports different illumination modes, including angle‑based distribution and projection onto a screen, enabling precise control of how light is shaped and delivered for various optical applications.
