His curiosity and interest in fine technology have led him to become a key contributor of the crafting of the highest quality projectors on the market.

Dominik Ruhdorfer has been a permanent part of the Light Engine Assembly Team since 2017. At that time, his brother was employed at In-Vision and told him more and more about the UV projectors for 3D printing and his work at family reunions. This made Dominik curious so he decided to apply for a job at In-Vision. The trained horologist (watchmaker) was immediately enthusiastic about the DLP projectors and their versatility.

"My ever-growing knowledge and the excellent cooperation with the teams allow me to continue to develop."

INV: Hello Dominik. It's good to see you!

Dominik: Thanks likewise. I'm glad to be able to tell you something about myself and my work.

INV: I understand that you originally received an education in horology. Watches certainly have a special appeal, so what brought you to precision engineering and what was particularly interesting to you about Light Engines compared to watches?

Dominik: After my apprenticeship as a watchmaker, I worked in this profession for another 10 years. My little brother brought the enthusiasm for UV projectors home with him at that time and my interest grew. When I started at In-Vision, I of course didn't know what to pay special attention to, but through a close cooperation with the quality department I was able to find a quick connection to the product. What started then with pure curiosity became a great passion for DLP Light Engines.

INV: Today, almost all projectors pass through your hands. You are responsible for assembling the individual components. What does your work process look like?

Dominik: I receive the individual components from the warehouse and assemble them into the modules. The components are then assembled into a finished Light Engine. After that, the UV projector will be tested. I also assemble cinema lenses from the individual components. For this, the cooperation with the coating is particularly relevant for me. Recently, I have also become involved in the testing process of cinema lenses and Light Engines. I was already interested in this from the beginning, and my ever-growing knowledge and the excellent cooperation with the teams allow me to continue to develop.

On our website we say: „Replacing the LED of your light engine has never been easier“and that’s a true fact.

INV: So you also assemble the components that Patrick, from our last interview about optics precision, produces. What made you particularly interested in working at In-Vision?

Dominik: Both as a horologist and as an assembler of a Light Engine, you have to be gifted with fine motor skills. I have always enjoyed creating something with my hands. At In-Vision, I can completely focus on the product. Seeing the whole process, from the individual components to the finished result, is really special.

INV: Speaking of product, what is your favorite product and why?

Dominik: I think all projectors have their appeal and strengths. I especially like assembling the most powerful UV projector "Helios". It is great fun for me because every part can be changed without having to disassemble the device. For example, the prism can be changed in just a few steps. Lenses can also be changed, or the illumination module. That is outstanding. On our website we say: „Replacing the LED of your light engine has never been easier“and that’s a true fact.

"The manufacturing processes have become more sophisticated over time, resulting in extremely high quality. "

INV: How have the Light Engines changed or developed in your eyes over the last 5 years?

Dominik: The products have evolved a lot. Our production capacities have expanded significantly, and the requirements have become much more specific. The manufacturing processes have become more sophisticated over time, resulting in extremely high quality. I really appreciate what the products can do. I already mentioned the modularity of our systems, which I think is a really smart feature, because it can expand the lifetime of our systems. It becomes cheaper for the customer in the long run to invest in a high-quality projector. And the technology is generally really exciting. All the precision efforts we put into our products are the reason why the quality of the image coming out is so high. Our attention to quality and precision combined with robust production processes also enables us to offer customized solutions. For example the wavelength and the lens can be customized exactly to the customers’ needs. In-Vision’s UV projectors are not a mass-produced product but customized high performance Light Engines. It makes me proud to be able to bring something so unique to life.

INV: Your enthusiasm is contagious. It's obvious that you've become an expert. To give our readers a little private insight, I would like to know what you like to do in your spare time.

Dominik: I see myself as a very family-oriented person and enjoy spending my spare time in the fresh air with my dog. In the summer I especially like to go to festivals where I like to improve my juggling skills. That is the best balance for me.

INV: Thank you Dominik for your time and for giving us an insight into your field of work and also your personality. In those interviews it always points out, that not only IN-VISION’s Light Engines are unique.
