4D Technology, an Onto Innovation Subsidiary

4D Technology, a subsidiary of Onto Innovation, designs and manufactures optical surface gauges and surface roughness profilers for accurate 3D, non-contact, high-resolution measurement of precision surfaces. Measure blades, fir-tree roots, and other critical components of rotary- and fixed-wing aircrafts in < 1 second with one-button operation that can be used anywhere in the factory, lab or even in the field - either handheld or combined with collaborative robots for high-volume automation.

Reduce scrap and rework and improve labor utilization and turn-around times with our industrial portfolio for aviation & aerospace engine manufacturing and MRO, including:
• 4D InSpec – a handheld, 3D surface gauge to quantify features and defects from 0.1 – 100mils deep.
• 4D InSpec XL – a 3D surface defect gauge with an expanded measurement area.
• 4D InSpec AT - a fully automated 3D, optical inspection system to measure features such as chamfer, radius, and edge break, and defects such as pits, dings, corrosion and scratches.
