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. WebOptical areal surface topography measuring instruments are powerful and flexible tools of a complex design, which makes them difficult to calibrate. Because the calibration process is an essential part of quality control during production it is very difficult for an industrial user to exploit the benefits of these instruments. cire trudon nazareth candle https://gpstechnologysolutions.com
