OPTICAL METROLOGY

4D Fizeau and Twyman-Green dynamic laser interferometers measure despite vibration, enabling challenging measurements in clean rooms, in environmental chambers, over long paths, and in remote locations.

4D portable optical profilers measure surface roughness down to the super-smooth regime. Non-contact, vibration immune measurement systems can be handheld, robot mounted, or even placed directly on large test surfaces for incredible flexibility.

4D polarization-based sensors have enabled scientific discoveries in fields ranging from astronomy to biomedical to oceanography. Compact, fast and field-proven, these unique cameras enable a range of image enhancement techniques and polarimetric measurements.

4D’s 4Sight Focus wavefront analysis software is the industry leader for measurement speed and ease of use. Whether you’re controlling a 4D instrument or analyzing data from any interferometer, 4Sight Focus gives you dozens of analyses, extensive 2D and 3D displays, filtering, data masking, fiducial alignment, diffraction analysis and much more.
