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. You can also use PolarCam snapshot micropolarizer cameras to inspect polarization quality of polarizer films.
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.
NanoCam HD systems measure surface roughness on coated and uncoated precision surfaces to ensure the quality of polishing processes.
PolarCam Polarization Cameras
Measure stress-induced birefringence on lenses, glass, bottles and more.
