3D Industrial Metrology Systems
Ultra-precise 3D laser scanning and measurement systems for dimensional verification, reverse engineering, and quality assurance
What is 3D Industrial Metrology?
3D industrial metrology involves the precise measurement of physical objects in three dimensions using advanced laser scanning and optical technologies. These systems capture millions of data points to create accurate 3D models that can be compared against CAD designs for dimensional verification. Using structured light or laser triangulation, metrology systems measure complex surfaces with sub-micron precision.
ASC International's 3D metrology systems provide sub-micron accuracy for applications requiring the highest precision. Our laser scanning technology enables non-contact measurement of complex geometries, reverse engineering of existing parts, and comprehensive quality control documentation. These systems are essential for measuring coplanarity on PCBs, verifying component dimensions, and analyzing board warpage.
Applications include first article inspection (FAI), tool and die verification, flatness analysis, and GD&T (Geometric Dimensioning and Tolerancing) reporting per ASME Y14.5 and ISO 1101 standards. Systems provide NIST-traceable calibration for regulated industries including aerospace, medical devices, and automotive.
