• Name: Optical Profilometer (Taylor Hobson/Talysurf CCI)
• Tool No.: MNCF 016
• Make : Ametek

Profilometer is a measuring instrument used to measure surface profile, in order to quantify its roughness. Critical dimensions as step, curvature, flatness are computed from the surface topography. An optical profilometer is a non-contact method for providing much of the same information as a stylus based profilometer.

Optical profilometer uses Principle of Coherence Correlation Interferometry (CCI) in surface topography measurements. The CCI methods are based on the cross-coherence analysis of two low-coherent light beams, the object beam being reflected from the object , while the reference beam is reflected from a reference mirror.
