4D Technology Corp An Onto Innovation Subsidiary

• Booth: 1625

4D Technology, an Onto Innovation subsidiary, 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®: the first handheld, precision instrument for non-contact surface defect measurement, with a measurement area of 8mm x 8mm. Now with improved resolution down to 2um! • 4D InSpec XL®: a surface defect gauge with expanded measurement area of 16mm x 16mm and improved resolution down to 5um! • 4D InSpec SR: the industry’s first portable, nm-level resolution surface roughness system for precision machined surfaces, enabling high-resolution 3D (areal) roughness right on the shop floor.
