A non-contact profilometer is a device used to measure the surface profile of an object without physically touching it. It employs techniques such as laser scanning or white light interferometry to capture detailed information about surface features, including roughness and texture. This technology is essential in various industries, including semiconductors and automotive, where precision is crucial. These profilometers are advantageous because they prevent damage to delicate surfaces and allow for quick measurements. They can analyze a wide range of materials, from metals to polymers, making them versatile tools in quality control and research applications.
