This system fully characterizes the performance of large optical flats, such as TV and computer screens, in a fully automated manner. Numerous safety features were incorporated that prevent damage to the optic during measurement process. A report is generated at the end of the test that provides a map of any defects on the optic and numerous other quantitative data that fully characterizes it. High accuracy servo driven translation stages allow for years of continuous use in a production environment with intuitive user friendly software. Defects as small as 1 micron can be detected (the diameter of human hair is about 100 microns). The system includes a motorized XY stage with dual cameras. One camera inspects for defects. The other camera is used at the operator’s discretion for close up views of the defects.
