3D Optical profiler is an interference microscopes, suited to measure the height variations as well as surface roughness. It has great precision as it uses the wavelength of light as the ruler. This enablesquantitative, ISO-compliant and precise surface measurement as well as description of micro- and nano-scale surface features. 3D Optical profilerruns into all application's requirements, such as precision, vertical range, speed, automation, and flexibility.Their process is non-contact and the measurements are three dimensional. Its task is to provide measurement script and perform the auto test. It works as an essential measuring device that has high utility and durable construction.
