Join 4D Technology in Huntsville, Alabama, August 11-13, 2026, at the 2026 Space & Missile Defense Symposium!

Stop by our booth #S3409  and learn more about our optical metrology technologies, including:

• AccuFiz Fizeau interferometers: Compact, high-performance Fizeau interferometers for shop-wide optics measurement at visible to SWIR wavelengths.
• AccuFiz D and Duo interferometers: short coherence Fizeau interferometers for measuring thin, transparent, plane-parallel surfaces < 0.2mm apart without the need for coating.
• PhaseCam: vibration-immune Twyman-Green interferometer with high power for measuring large optics and systems, and for long measurement paths. Its super-fast single-frame data acquisition enables measurement despite vibration and turbulence
• IR Systems:  Measure at wavelength with our PhaseCam and AccuFiz IR systems.  NIR – SWIR – MWIR – LWIR
• NanoCam HD: a small, non-contact optical profiler for vibration-immune roughness measurement in challenging conditions
