Video: The secret of Optical Design
In our third episode of videos techscout Maggie will give you an insight into how high precision optics are designed and manufactured. Meet one of the founders of In-Vision, Wolfgang Pferscher.
Only a few companies in the world have the know-how to design and manufacture high-precision optics. One of them is In-Vision. Follow Maggie through the production line to learn more about our lens production and lens assembly.

Optical design is both science and art—a discipline where theoretical physics, engineering constraints, and real-world performance converge. This deep dive into In-Vision’s approach to optical system development reveals the complex process behind creating high-performance projection solutions used in cutting-edge fields like 3D printing, lithography, and metrology.
Insights from experienced optical engineers illustrate how challenges are transformed into functional, scalable systems that push the limits of digital light.
More than just a look at design software or simulation tools, this piece highlights the human creativity and iterative testing behind every product. It’s a celebration of precision, problem-solving, and the often unseen craftsmanship that powers the world’s most demanding optical applications.
