Primary Optical Metrology Partner of NASA
4D is proud to be one of the primary metrology partners in the development of the James Webb Space Telescope, and on dozens of other projects to explore space and understand our planet.
Extreme environments
Cutting edge aerospace and defence optics are being lab-tested under field conditions. Field conditions may include cryogenic freezing, turbulence, vibration, vacuum conditions and more.
Because 4D’s dynamic technology is the best way to obtain good measurements in extreme environments, we offer the best choices and the greatest experience in measuring in these circumstances.
Products to Characterise Space-Bound Optics
PhaseCam
4D PhaseCam Twyman-Green interferometers are the industry choice for measuring concave spherical optics, from several millimetres to tens of meters in diameter.
PhaseCam systems can measure over long path distances despite air turbulence, and into environmental test chambers despite the heavy vibration from pumps associated with the chambers

AccuFiz
4D AccuFiz Fizeau interferometers can measure flat, concave and convex spherical optics, with a wide range of reference optics to match test parts.
High resolution systems like the AccuFiz 6MP can measure steep slopes They can measure through view ports to test optics at cryogenic temperatures in vacuum chambers.
