On-line Haze Measurement OHM

During the haze and transmission measurement a sample passes the slot of an integrating sphere, so that parallel light can illuminate the sample. The following intensity of the scattered light can be collected by a high-precision sensor. Beams with dispersion angles exceeding a standardised value cannot leave the sphere through the exit and are reflected by the spheres surface. The intensity of the scattered light is measured alter multiple reflections within the integrating sphere. The functional measurement principle of the OHM complies with the standard ASTM 1003.

The measurements are directly shown as percentages on a display and therefore provide an objective indication of quality instead of a visual subjective assessment.
