4D Technology’s handheld optical gauges are engineered to be vibration-insensitive, enabling ultra-fast 3D surface measurements in less than 10 microseconds—right on the shop floor.

This white paper explores today’s common approaches to defect and roughness measurement and the challenges they pose for machine shops and manufacturing facilities, including issues of accuracy, efficiency, and the complexity of measuring intricate parts and geometries. It provides an overview of the 4D InSpec and 4Di InSpec SR technologies, designed specifically to overcome these obstacles, and concludes with insights on how these systems can be automated to boost throughput and productivity.
