abstract

The retina camera is a very classical setup, which is mainly caused by the complex functional demands of this kind of systems. A lot of knowledge and experience is necessary in order to get the system parts working perfectly together at all multiple settings, so major changes in design will cause a new learning process. In example a lot of effort is paid to avoid undesirable reflected light, since the response of desired information of the retina is very weak and every direct reflex even from antireflection coated surfaces will overlap the desired information. The most disturbing undesirable reflected light is introduced by the so called ophthalmic lens, a refractive optical element dealing the double pass characteristics of the setup. Substituting the refractive optical element by reflecting surfaces will avoid the undesirable reflected light just by choice of the setup. It will be discussed the optical design concept of such a reflecting ophthalmic group, including the core idea and the steps leading to the final solution using reflecting free form surfaces. Furthermore, it will be shown the results of the related optical design study dealing the demands of the application retina camera.
