Optical Research Group

Archiv novinek.


The Optical Physics Group runs various labs with an overall area of more than 300 m2. Besides several classical optical labs equipped with optical tables, lasers, and appropriate optical components there are labs for laser beam and electron beam lithography, chemical labs for research, development, and processing of optical recording materials, matrology labs, optical labs for students and education, etc. The complex of labs contains complete technology for fabrication of diffractive structures with high resolution from the design to final replication processes.
