Optical Anti-Soiling Coating
Optical Coating Minimising Dust Optical Impact
Multi-layer optical coating designed to maintain solar / RF transmittance even with thin dust accumulation, reducing the operational impact of remaining dust.
Purpose
Multi-layer optical coating designed to maintain solar / RF transmittance even with thin dust accumulation, reducing the operational impact of remaining dust.
Context
Child of L2-DST-COAT within the Lunar Ark system
Principles
- ▸Index-matching layers reduce scattering by adhered particles
- ▸Anti-reflective coating maintains solar absorptance
- ▸Solar-reflective coating tested on EDS (NASA 2024)
- ▸Compatible with EDS overlay
- ▸Long-life inorganic stack
Typical implementations
- ▸NASA solar-reflective coating tested on EDS (2024)
- ▸Anti-soiling solar panel coatings (terrestrial)
- ▸Mars rover optical anti-soiling
Lunar considerations
- ▸Reduces sensitivity to thin dust layers
- ▸Combined with active cleaning
- ▸Long-life vacuum/UV-stable
