WELCOME TO OUR CLIENTS AND PARTNERS.

Although we are a hardware manufacturer, knowledge is the core of our company. We cultivate knowledge transfer and expansion in our company. Employees are constantly trained and exchange their knowledge and best practice. We take part in and co-organize conferences, publish articles and give presentations worldwide.

We are at our best when we closely interact with our customers, understand their application and optical design. This helps us help our customers with our knowledge about custom optical filters and optics in general. The most successful projects are the result of an open atmosphere and deep discussions with our customers – of course after signing a mutual non-disclosure agreement because often we reveal details about our design and production processes.
