For ideally diffuse illumination or to reference transmission, the Zenith Diffuser is the material of choice. The creation of diffuse illumination is necessary in lots of optical areas and can easily be realized with this special material. The light is ideally and homogeneously diffuse over the whole region from 250nm to 2500nm. Zenith Diffuser will often be used in front of detectors to eliminate directional components. We offer Diffuser thicknesses from 100 µm up to 2mm.
