Optical surface roughness
WebUnderstanding the surface roughness of optical surfaces is critical to control light scatter, as scatter can be proportional to the surface roughness of the optics. Light scattering and absorption from surface roughness have a significant impact on applications such as high-power laser systems, which can negatively impact the efficiency and ... WebTypical roughness measurements are performed using stylus profilers, non-contact optical profilers, or scanning probe microscopes (SPM). Stylus measurements are widely used for surface roughness, but they lack lateral resolution due to the tip geometry. They also may cause surface damage due to high forces exerted on the surface. Optical ...
