Patented dynamic interferometry and spatial carrier phase shifting enable high-resolution 3D surface and wavefront measurement in production environments, flightlines, vacuum/cryo chambers, and field deployments without vibration isolation.
Product overview
4D Technology offers a comprehensive portfolio of vibration-insensitive optical metrology and industrial measurement products. The product line includes three core categories: Optical Metrology products (PhaseCam Twyman-Green interferometers, AccuFiz Fizeau interferometers including SWIR and Duo variants, and NanoCam HD optical profilers) used for precision optics testing in astronomy, aerospace, defense, and semiconductor applications; Industrial Measurement products (4D InSpec, 4D InSpec XL, 4Di InSpec AMS automated system, and the new 4Di InSpec SR roughness measurement system) designed for shop-floor surface defect and roughness inspection; and Analysis Software (4Sight Focus for interferometers and 4D InSpec Analysis software) providing data acquisition, analysis, and reporting capabilities. The products share patented vibration-immune technology enabling measurements in challenging environments, with modular configurations supporting handheld, workstation, and robot-mounted deployment across industries including aerospace, aviation, automotive, semiconductors, and precision machining.

Through its Orbotech and inspection business lines, it addresses wafer/patterned wafer inspection and metrology — direct overlap with 4D's AccuFiz SWIR semiconductor wafer metrology applications.
Others
- Onto Innovation: Onto Innovation is the publicly traded parent company of 4D Technology (NYSE: ONTO). While not a competitor, it is the corporate context for 4D — Onto Innovation is itself a semiconductor metrology equipment leader, and 4D's products extend and complement Onto's portfolio.
Emerging players
- OptiPro Systems: OptiPro Systems is a precision optics manufacturing and metrology equipment vendor. It is both a partner (SI for 4Di InSpec AMS deployment) and partial peer in integrated metrology cells for aerospace and optics manufacturers.
- SensoLogic (Nd:YAG-based interferometry): SensoLogic is a niche developer of interferometric optical metrology technology. As an emerging player in the same dynamic interferometry category, it is a comparable (if smaller) technology competitor to 4D's spatial carrier phase shifting approach.
