Quality measurements for optical grade surfaces are typically completed in tightly controlled laboratory environments, with vibration isolation tables, expensive air handling equipment and careful temperature control. Instantaneous laser interferometer measurement, made possible through 4D's Dynamic Interferometry® technology, brings optical measurement right to the factory floor, despite vibration and turbulence. Shop floor measurement saves handling time and reduces the risk of damage to optics during handling, for highly efficient process control and quality verification.
