For the production of display glass, glass sheets with a homogeneous thickness profile are required. White light interferometers from Micro-Epsilon are used for high precision thickness monitoring, which determine the thickness without contact and from one side. Due to their high measuring rate, the sensors are also applied in high speed processes.

A decisive advantage is the distance-independent measurement, in which a nanometer-precise thickness value is achieved even with moving objects. The large thickness measuring range enables the measurement of different types of glass such as flat glass, display glass and laminated glass.
