Roughness measurement: Optical vs. contact stylus profilometry

WebOptical profilometry is a rapid, nondestructive, and noncontact surface metrology technique. An optical profiler is a type of microscope in which light from a lamp is split into two paths by a beam splitter. One path directs the light onto the surface under test, the other path directs the light to a reference mirror. WebOptical Profiling. If you need to characterize features at micrometre to sub micrometre on natural or manufactured surfaces, an optical profilometer will provide 3D surface metrology without any – potentially destructive – surface contact. This is a crucial advantage of optical profilometry over tactile (stylus-based) techniques. dhp jett junior twin metal loft bed white
