Watch this tutorial video on YouTube to learn more about telecentric illumination

What is telecentric illumination?

Precise microstructuring of photoresists requires a telecentric UV light source. All our UV-LED exposure systems are based on the telecentricity principle. But what exactly does this term mean?

With this tutorial video we want to explain telecentric illumination in a simple and practical way. The demonstration – made with a white LED – helps you understand the advantages of telecentricity for photolithography processes.

We hope you will enjoy this video of technical popularization that we intended to be accessible to a wide audience.

At the end of the video, we mention a Technical Guide that is freely downloadable on our website.
