CMM vs Vision System vs Optical Comparator
August 25, 2026
Quick Answer
A CMM is typically the strongest choice for complex 3D dimensional inspection, including multiple datums, internal features, and GD&T requirements that can be evaluated with tactile or other compatible sensors. A vision measuring system is especially useful for small, delicate, intricate, or high volume parts that benefit from non-contact optical measurement and automated, repeatable inspection. An optical comparator is often the simplest and most affordable option for visual inspection of 2D profiles, edges, angles, radii, and other silhouette geometry. The right system for your...
