Planness measurement of display glass

Thinnest glass of outstanding flatness is required for the production of displays for telecommunications equipment. During glass production measuring and monitoring of the flatness is a decisive factor for quality inspection. The results of these measurements can be used for optimising the pro-duction process. On a high-precision hard rock table in the measuring room samples of these thinnest glass plates are measured by laser-optical triangulation sensors with an accuracy of 5 μm.
