Today, the use of modern optical technologies is a prerequisite for a large number of innovative applications in the fields of electrical, medical and mechanical engineering as well as life sciences. Both industry and research companies benefit from optical metrology as a key technology. However, the spectrum of technical optics goes far beyond this: developments in the fields of biomedical optics and ophthalmic optics, laser technology, lighting technology, microsystems technology and optics for communication and sensor technology play an important role for many medium-sized companies in order to meet the increasing demand for high-precision, flexible and fast solutions.
