Core offering

4D Technology designs and manufactures vibration-immune optical metrology instruments — including Twyman-Green and Fizeau laser interferometers (PhaseCam, AccuFiz), the NanoCam HD optical profiler, and the 4D InSpec / 4Di InSpec family of handheld, workstation, and automated shop-floor surface inspection and roughness gauges — along with 4Sight Focus and 4D InSpec analysis software. 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.
