These demanding applications place exceptional demands on our systems and require the highest precision and reliability.
With years of experience in the industry, we have developed the know-how and expertise to master even the most complex challenges. Our first-class solutions are characterized by their durability and robustness and meet the highest quality standards.
Our development department works closely with leading scientific institutes to stay at the forefront of technological development.


Innovative customized precision optics
We develop and manufacture highly robust precision optics that meet the highest standards of reliability and long-term stability.
Defense: Development and production of optical components and systems for night vision, thermal imaging, line-of-sight, surveillance and target location systems.
Aerospace: Our optical systems, developed and manufactured according to customer requirements, are used in satellite orientation in space as well as in weather and environmental observation.
In order to withstand extreme conditions such as special pressure conditions, strong temperature fluctuations and high acceleration loads, we rely on special glasses. Our optical systems are equipped with radiation-resistant coatings that guarantee high resistance to environmental influences. We also integrate intelligent mechanical solutions that ensure precise alignment and stability of the optics even under extreme conditions.
