500nm Glass Step Height: Extreme Accuracy with Non-Contact Profilometry

Surface characterization are current topics undergoing intense study. The surfaces of materials are important since they are the regions where physical and chemical interactions between the material and environment occur. Thus, being able to image the surface with high resolution has been desirable, since it allows scientists to visually observe the smallest surface details. Common surface imaging data includes topography, roughness, lateral dimensions, and vertical dimensions. Identifying the load bearing surface, spacing and step height of fabricated microstructures, and defects on the surface are some applications that can be obtained from surface imaging. All surface imaging techniques, however, are not created equal.
