Understanding Surface Roughness Edmund Optics

WebWith a contact-type roughness meter, surface roughness is measured by tracing the probe across the surface of the target. In contrast, a laser-based non-contact roughness meter emits a laser beam onto the target and detects the reflected light to measure the roughness. The direction of measurement is the key to successful measurement.
