4D Technology Corporation

4D Technology will be showcasing our 4D InSpec and 4D InSpec SR at this year’s Precision Machining Technology Show (PMTS) in Cleveland, Ohio. On April 1-3, join us at booth #5109 for tool demonstrations to see firsthand how user friendly these tools are. The 4Di InSpec? SR employs patented technology for rapid surface measurements unaffected by vibration. It can measure in any orientation, across a variety of applications and can tackle metrology challenges like: ~3D roughness of hard-to-reach areas and large samples ~3D roughness in any orientation – right on the shop floor ~Automating 3D roughness measurements ~Integrating 3D roughness systems into process machining systems Learn more about PMTS here:?https://lnkd.in/gfaWku6N

Two weeks away! Register now for our free webinar, Shop Floor Surface Finish Measurement with 3D Optical Technology, on April 2: https://lnkd.in/esWCd7dt

The 2025 Compound Semiconductor Magazine & CS International Conference is just a few weeks away in Brussels, Belgium, and Onto Innovation’s Mike Rosa will be on hand to deliver the presentation “High Sensitivity & Throughput Defect Inspection Technologies for SiC and GaN Power Technologies.” In his presentation Mike will address a few of the more fundamental challenges that can occur in the production of SiC- and GaN-based devices at larger wafer sizes. In addition, he will explore several solutions, including the Celero? PL, for critical process steps. The Celero PL system is designed to fulfill the need for subsurface defect inspection and classification capability for silicon carbide (SiC) and gallium nitride (GaN) based wafers and compound semiconductor materials. Available with a range of wafer handling options offering the ability to meet both R&D and high-volume production needs while providing best in class throughput and sensitivity at the lowest cost of ownership per pass.

Join 4D Technology for a free webinar, Shop Floor Surface Finish Measurement with 3D Optical Technology,?on Wednesday, April 2. Until now, companies have typically relied on 2D stylus-based systems or expensive, non-portable optical profilers that can be time consuming and extremely sensitive to environmental factors, typically confining them to extremely quiet vibration isolated lab environments.?Optical profilers have the added burden of being stationary and therefore limited in sample sizes and geometries that can be measured. This exclusive webinar demonstrates how to take advantage of our rugged, portable roughness system to provide 3D surface finish measurements with nanometer resolution right on the shop floor.

To keep pace with the growth of data-heavy applications, government and space agencies are investing heavily in free space laser communications. Using multiple wavelengths, laser sources can increase data transfer rates far beyond the capabilities of radio-frequency (RF) communications. But developing those data links requires optics that push the capabilities of today’s manufacturing techniques— and the metrology to verify them. 4D Technology’s metrology systems are leading the way, controlling wavefront error, surface figure, and surface roughness at the wavelength bands that matter the most.

4D Technology plays an important role in assuring the functionality of space-based and terrestrial telescopes. “Every optic in that telescope [James Webb Telescope], the optics in the cameras, the spectrometers that are used in that telescope, the actual structure that holds the telescope, every aspect has been tested with interferometers from 4D Technology."
