This article explains the benefits of the non-contact inspection method used by 3D optical profilers, and outlines the best practices and measurement results for some specialized PTB ...

A micrometer is a useful instrument used by engineers and metrologists in almost all industries for very precise and accurate measurements. They are extensively used for essential metrological ...

Deflectometry is an advanced optical metrology technique designed to evaluate the three-dimensional (3D) shape of specular, mirror-like surfaces. By analysing the deformations in reflected patterns, ...

Surface profile gauges are used to measure the profile height of a surface. The degree of the surface profile affects a coating’s overall performance and determines aspects such as adhesion, coverage ...

The measurement technique of the aspheric surface is mainly for the surface form and parameters. The surface form is the three-dimensional distribution of the surface in the spatial domain. The ...
