Greater clarity in glass and transparent materials
You’re on the hunt for suitable solutions for your applications where you measure glasses or other transparent materials. Why don’t you take a look at the surface measurement systems from Polytec? These product lines offer you flexible and easy-to-use systems for measuring thickness or determining form parameters such as flatness.
Polytec also offers you customized solutions depending on roughness, distance or thickness requirements. If you’d like to perform measurements quickly right there on the production line, then the chromatic confocal TopSens and TopLine products are ideal for your application. But if you’re looking to carry out an areal thickness analysis at millions of points, then you should opt for the TopMap series.

Measure surface flatness on glass
Determining surface flatness is extremely important for the functional use of many glass products. This involves characterizing flatness for the most diverse areas of use. Whatever the application, Polytec offers you the opportunity to quickly and reliably check how flat your glasses are. Large-area measuring white-light interferometers such as the TopMap Metro.Lab or the TopMap Pro.Surf and Pro.Surf+ record the flatness of large areas quickly and with maximum precision – no matter whether you’re working in your metrology lab or close to production. TopMap surface metrology are developed for use close to or in production lines. These surface profilers can continuously record height data at selected points in real time for immediate feedback regarding the production process.

TopMap Metro.Lab
Being a complete measuring station, the TopMap Metro.Lab is ideally suited to large-area topographies on almost all surfaces. Since it offers great value for money, it is also attractive for smaller companies with fewer tasks.

TopMap Pro.Surf
Ideal for quick and precise 3D surface characterization. The areal measurement ensures that no details are overlooked. Short measuring times and a large field-of-view characterize the TopMap Pro.Surf.
Keeping Layer Thickness Constant
The material thickness of transparent surfaces is critical for both their fitting accuracy and function. Checking it by performing measurements and constantly maintaining the exact same level is indispensable if high quality and a low rejection rate are to be achieved.
The TopLine system from Polytec should be your first choice for this task. It provides you with material thickness readings at 180 points – effectively in real time. However, if you need fewer points, then opt for the TopSens point sensors. These products boast an even more compact design and can easily be tailored to customized requirements. If your job involves performing an areal analysis of how thick a transparent sample is, then Polytec’s TopMap series is perfect for you.
A Practical Example:
As an example example, Polytec’s surface measurement systems are used to check and maintain the thickness of cell phone displays during production.
