Contamination of optical elements by lubricant condensation in satellite systems
Kontaminace optických prvků kondenzací maziva v satelitních systémech

Aim of thesis: Comprehensively analyze the mechanisms of contamination of optical elements in satellite systems caused by lubricant condensation and propose measures to reduce their negative impact on optical performance and long-term system reliability. Sub-objectives: Study the processes of contaminant transport (gas phase, redeposition) within satellite structures and their interaction with optical surfaces. Experimentally verify the effect of condensed lubricants on optical properties (transmissivity, reflectivity, scattering, degradation of surface layers). Develop or adapt experimental methodology for simulating contamination phenomena under laboratory conditions (vacuum, temperature cycles, UV radiation). Quantify the temporal degradation of optical performance depending on the type of lubricant, optical element material, and operating conditions. Compare different types of protective coatings and surface treatments of optical elements in terms of their resistance to contamination.

Connection to the ESA project dealing with labyrinth seals. Cooperation with the BrnoSAT satellite development project and participation in its operation. Opportunities for internships and participation in ESA conferences.
