The 3D Optical Nano Profilometer device made by the Fath Noor Mihan knowledge-based company is a highly developed optical device of nanoscale 3D measuring instruments. Based on the interference principle, this device operates in two modes of white light microscopic interferometry and phase displacement interferometry. Furthermore, it measures the shape and roughness of surfaces on the nanometer scale accurately. This device is completely non-destructive and does not cause any damage to the understudy sample because of the optical working mechanism. Besides the accuracy and reproducibility on the nanometers scale, higher collecting data rate, greater field of view and the possibility of measuring larger roughness without reducing accuracy are the strategic features and advantages of this product compared to devices with similar uses.
