O-ring segment measured with an optical profiler

An O-ring presents a challenging surface texture measurement. Radial profile, steep sides, small cross-section, soft material…while the measurement is virtually impossible with a stylus, it is possible with a 3D optical instrument.

This dataset is a great example of how the geometry/form fitting and filtering options in OmniSurf3D make it easy to analyze even complex shapes.

This blog post will show you how it’s done…try it for yourself!


Measured via: Zygo ZeGage Plus (10x, de-sampled 2x)
