4D Technology has been the innovator in metrology for optics and precision surfaces for over 20 years.
Our patented Dynamic Interferometry introduced an entire class of vibration-immune measurement systems.
It’s no surprise that virtually every space- and ground-based telescope for the last two decades has been tested with 4D instruments.
That same technology has enabled optics manufacturers to improve yield, reduce cycle times and ensure quality in manufacturing from high-volume flats to challenging aspheres.
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.
