Scattered light measuring technology
Measuring surfaces with the scattered light method means speed, high accuracy and a laminar evaluation of functionally-important components.
In this process the sensor illuminates the surface, depending on the application and sensor type with a measuring spot between 0.03 to 1.8 mm diameter. The light rays deflected with varying intensity according to the surface roughness, so that so that scattered light distributions that vary in width occur. In this process this distribution curve is the basic information for roughness, form and gloss.
