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.
For such tasks, Polytec surface metrology comes into play. It provides you with material thickness readings at 180 points – effectively in real time. If your job involves performing an areal analysis of how thick a transparent sample is, then Polytec’s TopMap series is perfect for you.
As an example example, Polytec’s surface measurement systems are used to check and maintain the thickness of cell phone displays during production.
