Learning outcomes
|
The aim of the lectures will be optical manufacturing process. Students will be acquaintance with basis of manufacturing documentation, with base shape generating procedures (milling, cutting), with grinding, polishing, coating techniques and with procedures of final inspection. The emphasis will be placed on both traditional (classical) methods of manufacturing and modern computer controlled subaperture procedures, which are applied in the production of aspheric and "free form" optical elements.
Students will acquire knowledge in the field of precision optical surfaces production, which primarily involves knowledges of different mainly glass materials grinding and polishing, and expertise in the field of wide range of physical quantities measuring used to characterize surfaces. Additionally, students will have basic knowledge in the field of quality control and waste management.
