Thickness measurement of displays and flat glass
For the production of display glass, glass sheets with a homogeneous thickness profile are required. For thickness measurement tasks, confocal chromatic sensors from Micro-Epsilon are used. These detect the thickness from one side without touching the target. Due to their high measuring rate, the sensors are also applied in high speed processes.
Gap monitoring of safety glass
For quality inspection and process control during the production of safety glass, confocal chromatic displacement sensors are used which offer a multi-peak feature. These enable thickness measurements to micron accuracy. The sensors detect up to 5 layers by evaluating 6 measurement values on the boundary areas. Therefore, the thickness of film, gap sizes, applied adhesives and coatings can be determined reliably.
Thickness measurement of medical container glass
Consistent thickness of walls and bottom are vital quality factors in medical container glass. In order to determine the glass thickness, confocal chromatic sensors from Micro-Epsilon are used. These sensors also measure very thin glass. Thanks to thickness calibration, the distance between the containers and the sensor can vary without affecting the measurement accuracy
Color measurement of glass
The color of glass is the crucial and visually distinctive feature of many different glass products. This is particularly true with natural and recycled raw materials based on varying compositions, where continuous and objective control of the color effect is a decisive factor in consistent, homogeneous quality. Color sensors from Micro-Epsilon are used in order to inspect colors and shades in the production process.
Multi-layer thickness measurement of display glass
In inline thickness measurements of display glass, the IMS5400-TH white light interferometers impress with their high measurement stability. Based on the multi-peak thickness measurement, up to 5 layers or air gaps can be measured simultaneously.
Position measurement when fitting precision glass
In addition to single-peak distance measurements, the white light interferometers are also used for multi-peak distance measurements. This means that both distance values and calculated thickness values can be used to control positioning tasks with maximum precision.
Plunger measurement in IS machines
In hollow glass production, IS machines are used. This production environment is characterized by harsh ambient conditions such as vibration, steam and high temperatures. Micro-Epsilon has developed an inductive EDS displacement sensor, which is specially intended for 24-hour operation in IS machines to determine the exact plunger position. The robust sensor design compensates for temperature influences, including those caused by temperature gradients along the measuring range.
Distance measurement on anti-reflective coated glass
After the coating process, glass with anti-reflective coating is inspected using laser-optical displacement sensors from Micro-Epsilon in order to determine undulations and torsion. The planarity of the coated glass surface is measured in several tracks. Based on the patented Blue Laser Technology, optoNCDT 2300-2DR sensors provide high measurement accuracies on coated glass surfaces.
