About us

We are a team of scientists and developers working at the Department of Experimental Physics, Faculty of Science, Palacký University Olomouc.

Our mission and passion are the application and development of nuclear physics techniques, particularly Mössbauer spectroscopy. We draw on decades of experience in this field, dating back to the 1980s (see our list of publications). Sales of our spectrometers to universities and industry help finance further development and upgrades, enabling better research results and more advanced equipment for both our research and our customers.

Our team includes specialists in materials research and nanoscience, focusing on the synthesis of functional magnetic particles, including iron ferrites and iron oxides, as well as plasmonic structures and metal-organic frameworks. We also benefit from close cooperation with chemistry departments at our university and institutions abroad.

Our work is not limited to the development of standard equipment. We are also active in nuclear quantum optics using a radioactive source of ⁵⁷Co, with research focused on polarized Mössbauer spectroscopy, single-photon entanglement and photon nonlocality.

All these activities drive us to continually optimize and improve our instruments, keeping them up to date and at the forefront of current scientific knowledge.

In addition to our equipment, we offer custom development of instruments and measurement procedures, as well as scientific collaboration.
