Stylus Profiler vs Non-Contact 3D Measurement System Comparison

This document compares stylus-based contact profilometry with non-contact 3D optical measurement systems, detailing their respective measurement methods, ranges, and sample preparation requirements. It covers key specifications such as cross-sectional shape measurement up to 200 mm, 3D area measurement up to 300 × 150 mm, and applications for soft, viscous, transparent, and rough samples.
