4D Technology, an Onto Innovation subsidiary
4D Technology designs and manufactures optical surface gauges and surface roughness profilers for accurate 3D, non-contact, high-resolution measurement of precision surfaces. 4D's gauges measure in < 1 second with one-button operation, and can be used anywhere in the factory or lab - either handheld, combined with collaborative robots for high-volume automation, or in-situ applications. Measure critical components with our industrial portfolio which includes:
- 4D InSpec® & 4D InSpec XL: the first handheld, precision instrument for non-contact surface defect measurement, with a measurement area of 8mm x 8mm or 16mm x 16mm and resolution down to 2um.
- 4Di InSpec AMS: a fully automated 3D, optical inspection system to measure hundreds of callouts in minutes! Quantify features such as chamfer, radius, edge break, and thread geometries and defects such as pits, dings and scratches.
- New! 4Di InSpec SR: the industry’s first handheld, nm-level resolution surface roughness system for precision machined surfaces, enabling high-resolution 3D (areal) roughness of hard-to-reach areas and large samples right on the shop floor.
