Flat panel display production requires accurate metrology at every step of the process. 4D PhaseCam interferometers have been designed to measure flatness and defects on glass substrates, while the NanoCam HD measures surface roughness and defects. 

Products for Displays

PhaseCam IR Interferometers

Compact, lightweight and vibration-insensitive for accurate surface and wavefront measurements at infrared (1.064 through 3.39 micron) wavelengths.

Optical Profilers

NanoCam HD  systems measure surface roughness on coated and uncoated precision surfaces to ensure the quality of polishing processes.
