    Entitled "International and digital subsurface-damage-testing technologies laboratory", the OpenLab for OCT will be present with an Invited Talk at EOSAM22 in Porto on the 13th of Septmeber 2022 at 4:30pm :

    With the establishment of a versatile infrastructure for subsurface damages, a new interational laboratory has been established. For this purpose, researchers from the fields of optical metrology, optics technology, ophthalmology and computer science joined forces. A central research question and object of object in the OpenLab are microcracks in optics production, so-called subsurface damage. With the ultra-high resolution and highly sensitive optical coherence coherence tomography, a measuring principle based on white light principle based on white light interferometry, it will be possible to in glasses and ceramics with a resolution of 1 μm. The laboratory is open to researchers and users to work together on topics related to SSD or to have measurement tasks carried out directly. The article presents the structure, the possibilities of cooperation and the goals of the open lab.

    MT/BT students receive funding for the development of a low-cost and imaging OCT (optical coherence tomography) system for teaching and research

    With their idea to develop a low-cost OCT system for teaching, the two master students Calvin Kreft and Konstantin Gramatte scored points with the members of the research committee. The funding is intended to promote student involvement in research and development at the Ernst Abbe University of Applied Sciences Jena (EAH Jena). To ensure that the two students do not lose their way, they are actively supported by Professor Dr. Iwan Schie.


    Optical coherence tomography (OCT) is an imaging technique for generating two- and three-dimensional images of depth profiles in organic and non-organic media, similar to ultrasound imaging. Due to the high axial resolution of about 0.5 μm to 15 μm and a simultaneously relatively high penetration depth of 1-3 mm, depending on the wavelength used, this method offers a wide range of applications, including medicine and materials analysis. Ophthalmology in particular benefits from the technological advances of OCT due to the high-resolution imaging, for example in the examination of the anterior and posterior segment of the eye.


    The project includes the development and setup of an OCT system, which explains the implementation of the imaging technique to students in a clear and practical way and enables a "hand-on experience" with this technique. This practical implementation opens up numerous possibilities in teaching for a practice-oriented university. These include the creation of numerous practical courses around this topic to deepen the basics of this imaging technique in medicine and materials analysis, as well as the practical use of 3D printers, which are gaining significant importance as time goes on.


    Invitation to the 21st Colloquium on Manufacturing Technology and the Inauguration of a New Machining Center for Optics Production


    Dear ladies and gentlemen, dear colleagues and students,


    We would like to invite you to the 21st Colloquium on Production Engineering and the inauguration of a new machining center for optics production on July 27, 2022, from 2 to 6 pm in Lecture Hall 7 of our university.

    The event will start with four presentations around precision machining of optical freeforms and their measurement. This will be followed by a live demonstration of the machining of a complex freeform, followed by the ceremonial commissioning of a new 6-axis polishing center.

    The acquisition of this equipment was made possible by a grant from the Deutsche Forschungsgemeinschaft e.V. (DFG) and the Free State of Thuringia. This means that the machine equipment for the entire process chain of optics production of complex components and free forms is now available at our university. It offers extended possibilities for joint development projects and the integration of innovative manufacturing technologies into teaching.

    At the end of the event, a joint meal with Thuringian specialties offers the opportunity to get into conversation, discuss ideas, network and exchange experiences.

    For planning purposes, please register via our website: Manufacturing Technology Colloquium and Ceremonial Inauguration of a 6-Axis Polishing Center -Event (


    Best regards,

    Marlies Patz & Jens Bliedtner
