The cooperation between POG Präzisionsoptik Gera GmbH (POG) and the Fraunhofer COMEDD in the field of OLED (Organic Light-Emitting Diode) microstructures for optical systems exists already for a while. For the first time at the electronica 2012 show they present OLED structures coated in the range of micrometers at opaque or transparent glass substrates, which can be used in complex optical and opto-electronical systems for measurement engineering, for industrial image processing, for medical applications, in laser, aerospace and semiconductor industry or for sports optics.

The aim of the cooperation is the development of transparent optical devices with stand-alone, self-shining single figures, points or lines. This is particularly interesting for applications in microscopes or telescopes. In contrast to the current state of the art - to couple in the luminous structures into the field of view e. g. via prisms -  the active luminous areas are now integrated directly into the glass substrate.

POG is able to add finest structures to glass substrates for optical instruments. These will be coated precisely with OLEDs at Fraunhofer COMEDD. Thus only the areas and information in the optical applications are lighting, which are required in order to guarantee that the field of view within the highly complex systems will not be limited unnecessarily. The Fraunhofer COMEDD and POG will present demonstrators with such fine structures – the smallest of them are visible only by microscope.

Dirk Schlebusch, development engineer at Fraunhofer COMEDD, explains: “Due to the development of OLED-coated micro structures on glass substrates, the system of information input – no matter whether it is a picture, symbol or information on a seven-segment-display - can be simplified enormously. In contrast to previous constructions, these structures are integrated directly into the optical path now. The costs for additional components, which were necessary for the input of the information so far, and the efforts for their integration and adjustment into the system can be saved now.“

A possible application could be a structured glass plate with variable structure sizes (5 µm up to 500 µm) for a resolution check or for the display of distance information via a seven-segment-display, which could be integrated e. g. into a telescope. The brightness of the luminous structures could be adapted to the ambient lighting via additional sensors.

"Through the products, which were developed in cooperation with the Fraunhofer COMEDD, we are able to provide absolutely new opportunities to our customers in the precision optical toolbuilding and in sports optics: Thus the newly developed modules can be used e. g. as resolution test structures in the field of measurement technology or as reticle in telescopes or binoculars.“ mentioned Ray George, Director Sales and Production at POG.
