If the number of participants is not too high, an oral examination is preferred over written exams.

Lowest competence level checked is knowledge. Questions could address the sign convention, the structure of the imaging equation in dependence of light direction, the definition of the principal ray or the labelling of optical components conforming to industry standards.

The next competence level is related to skills. Examination could be done by the task to draw the optical path of rays of optical systems whereas the qualitative correct position of functional planes is important. Furthermore calculations can be performed, e.g. the resolution of optical systems, the image shift in systems with regions of differing refractive indices, of the overall focal length of a compund system.

The highest competence level adressed is methodical expertise. It can be checked by a real world task: E.g. the design of a microscope with an own light source where some application paramters to achieve are given or some off the shelf components are given. In a guided discussion or guided calculation it can be found out easily, if the underlying principles are understood and can be applied proactively, if intellectual transfer is made and if there is sufficient overview.
