Diffraction optics is 1 of the areas of technology on which work is carried out at the Centre of Advanced Materials and Technology CEZAMAT of the Warsaw University of Technology. "We have developed technology from structure plan to modeling itself. We survey whether our structure agrees with our project, and then we can make them up to a fewer twelve copies a month. Their application increases the anticipation of optical glasses" - said Dr. Jarosław Suszek from the Faculty of Physics at Warsaw University of Technology.
