Why Choose a System from 4D Technology?

The 4D InSpec surface gauge is the first handheld, precision instrument for non-contact surface defect measurement. With 2.5 µm vertical resolution, portability, affordability, and ease of use, 4D InSpec puts high-resolution 3D surface measurement where it’s needed: on the factory floor, in machine shops, and field service applications.



4D InSpec instantly quantifies defects such as pits, scratches, nicks, dents, and bumps. It measures features such as edge break, radii, rivet depth, and shot peen depth from 2.5 µm to 2.5 mm deep for the Standard system and 2.5 µm to 9.0 mm for the XL system.

Applications for Optical Metrology Products

There is a wide and growing range of applications where the 4D InSpec tool is being effectively by industry. Here we explore some of the most common applications.

Aerospace components

High-value machined aerospace components such as landing gear components, and machined structural components are excellent candidates for the 4D InSpec tool to ensure that any defects are within specification so that these valuable components can be used in service.

Automotive components

4D InSpec with the new edge break functionality can help automotive component manufacturers, such as aluminium casting producers, inspect edge radii for conformance to specification quickly and repeatably.

Mining equipment components

With valuable components in the mining equipment sector the 4D InSpec system is helping maintenance groups quantify defects so that valuable components can be reused and put back in service, saving component costs and reducing downtime of key equipment.
