We started our company on July 1st, 2002. This decision was triggered off by the wish to return to the “more interesting things” in optics. Our work focuses on the design of lenses for applications in the fields of imaging, observation and illumination. Our approach is to bring together the personal experience that we have gained during many years of work in different companies in the field of optics. On the basis of this experience we feel well prepared not only for standard problems but also for tasks that make it necessary to leave the beaten track and find novel solutions.
About
Our service is the layout, design and realization of optical systems. The development is done in close cooperation with the customer in order to achieve tailor-made solutions that are optimum with regard to technical results as well as cost. Through cooperation with experienced partners we are also in the position to offer mechanical design and production of the developed lenses. Since early 2008 we dispose of measuring equipment so we can do the quality control of manufactured lenses in house.
