4D Technology has added to its line of PhaseCam dynamic interferometers, supported by the release of 4Sight Focus acquisition and analysis software
Measurement of large optics require metrology systems that can function despite vibration, turbulence and other challenges.Laser interferometry is used throughout the manufacturing of large optics to ensure conformance to demanding design specifications. More recently, “dynamic interferometry” has been implemented for vibration-insensitive measurement of large optics.
*Now available on demand* Dr Erik Novak, senior director of business development at 4D Technology, will discuss the different aspects that need to be considered when selecting a Large Aperture Interferometer.
