Stress measurement systems

Especially in measuring the mechanical stress in thin films we deliver different solutions developed for the tasks in the optical coating industry. Our products can easily measure the stress inside a thin film already during (in-situ) and after (ex-situ) the coating process. Also, the temperature dependence of the stress in the film can be analyzed up to temperatures of 400°C and more.


The service that we offer you is to rent one of our measurement systems for a certain time period. The easiest and most uncomplicated way for you is just sending your coated samples. Then we measure the stress or thermal coefficient of expansion of your thin films for you.
