Profilometry is a measurement technique used to analyze the surface profile of an object. It provides detailed information about surface roughness, texture, and topography, which are important for various applications in manufacturing, materials science, and quality control. Profilometers can be contact-based, using a stylus to trace the surface, or non-contact, using light or laser technology. This technique is essential in industries such as semiconductors, automotive, and aerospace, where precise surface characteristics can affect performance and durability. By understanding surface features, engineers can improve product design and ensure that components meet specific standards and requirements.
