    What to see

    A Robot Making Measurements! See how come dynamic measurements make automated positioning production-speed fast.
    Dynamic optical interferometers: compact, lightweight Fizeau and Twyman-Green interferometers measuring optics without vibration compensation.
    Polarimetry: Use a polarizing snapshot camera to measure polarization. See PolarView analysis software.
    Nanosmoothness: a portable optical profiler so fast you could mount it on a robot to measure anywhere you want to, non-contact, on your large optic.

    Booth 649

    Featuring: PhaseCam Twyman-Green Interferometer for optical shape and wavefront testing in any environment.

    4D Technology designs and manufactures dynamic laser interferometers, optical profilers, surface gauges and polarization cameras for non-contact metrology of precision surfaces, even in the presence of vibration. 4D interferometers acquire data in as little as 30 microseconds, at wavelengths from DUV through IR. Applications include aerospace, defense, astronomy, general optics, and more. 4D Technology is a Nanometrics business.
