Onto Innovation Inc. is proud to announce that its 4Di InSpec™ SR Surface Roughness Gauge was awarded the 2026 SPIE PRISM Award in the Test and Measurement category. The 4Di InSpec SR is an innovative, fully portable, vibration-immune, 3D surface roughness tester which non-destructively measures even rough surfaces with nanometer-level vertical resolution without the need for a controlled lab environment.

Each year, SPIE, the international society for optics and photonics, recognizes the top-rated new optics and photonics products with the industry-focused Prism Awards. Finalists and winners were selected by a panel of international judges who leveraged their knowledge and acumen from across the technology commercialization and funding sectors. The distinguished judges from eight countries included government-agency representatives, commercial business executives, academic researchers, and industry leaders.
Built on patented optical technology, the 4Di InSpec SR Surface Roughness Gauge revolutionizes precision inspection, delivering fast, vibration-resistant, scratch-free analysis across metals, composites, plastics, and more – right on the shop floor. With millions of data points and ISO-compliant parameters, it captures ultra-finished to corroded surfaces without replication. Its rugged design, one-button operation, and flexible mounting options – including robotic integration – enable access to hard-to-reach areas. Paired with 4Sight™ Focus software for intuitive control and seamless data transfer, the 4Di InSpec SR sets a new standard for automated, high-performance surface metrology.
“This award reflects the innovation, technical excellence, and dedication of our team,” said Craig Manning, VP & GM of Onto Innovation’s 4D Technology. “Like our other solutions, the 4Di InSpec SR represents a shared commitment to solving real measurement challenges with practical, purpose-designed solutions.”
Beta units of the 4Di InSpec SR are currently being shipped.
