AI Technical Summary
Existing coating technologies struggle to achieve uniform layer thickness distribution on substrates with varying curvatures and curvatures, especially in small batches, and are not easily automated, leading to inefficiencies and limitations in coating processes for optical and ophthalmic lenses.
A coating station with a planetary workpiece arrangement that includes a convex planetary system and an offset evaporation source, allowing for improved layer thickness distribution and reduced dependence on substrate radius and curvature, enabling small batch coating of substrates with high precision and flexibility.
The coating station achieves uniform layer thickness distribution with improved flexibility and efficiency, allowing for precise coating of substrates with varying curvatures, even in small batches, and is compact and easy to maintain, suitable for non-experts to use.
