Coretec Group gets research partnership with Australian university for high-tech glass

ANN ARBOR—The Coretec Group Inc., (OTCQB: CRTG) has partnered with The University of Adelaide, one of the world’s top universities in the field of applied glass science and photonics, to develop a glass to be used in The Coretec Group’s CSpace, a 3D static volumetric display technology. This project will be jointly funded by The University of Adelaide.

The University of Adelaide’s Professor Heike Ebendorff-Heidepriem, deputy director of the Institute for Photonics and Advanced Sensing (IPAS) and Director of the Optofab Adelaide Hub at the Australian National Fabrication Facility (ANFF) will lead the research. Ebendorff-Heidepriem is one of the world’s foremost researchers in the field of the development of novel optical glasses, fibers, surface functionalization, and sensing approaches.

Previous work in volumetric 3D displays have examined the use of low-phonon energy fluoride glasses such as ZBLAN; however, these glasses have been severely limited by the difficulty in producing them in large size and high-quality,” said Ebendorff-Heidepriem.

ZBLAN is the most stable, and consequently the most used, fluoride glass, a subcategory of the heavy metal fluoride glass (HMFG) group. The name is an acronym of its composition, 53% ZrF4  (zirconium tetrafluoride), 20% BaF2 (barium fluoride),  4% LaF3 (lanthanum triflouride), 3% AlF3 (aluminum fluoride), and 20% NaF (sodium fluoride).

This research project will examine alternative low-phonon energy glasses such as tellurite and germanate glasses that have a greater potential for large-scale manufacturing. The development of these glasses will be led by Yunle Wei, who is a glass scientist in Ebendorff-Heidepriem’s team. The project will include characterization of the performance for volumetric display.

“In order to develop new glasses for an image chamber, we rely on experts like Professor Ebendorff-Heidepriem and her team who have the scientific expertise and the experience to generate alternative glasses to continue our improvements in our 3D volumetric display,” said Matthew Kappers, CEO of Coretec Group.

The Institute for Photonics and Advanced Sensing was created to bring together experimental physicists, chemists, material scientists, biologists, experimentally driven theoretical scientists, and medical researchers to create new sensing and measurement technologies.

A volumetric display device is a graphic display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects.
