Lotus flower effect
 
A principle from nature: The lotus flower effect.That is the water repelling characteristic of surfaces, to simply let water drops pearl off and to repel dirt. LotuTec acts as protective coating and cleaning and care is made especially easy.
This technology has been used by Carl Zeiss for millions of spectacle lenses for a long time.

Without LotuTec
 
As with most leaves, moisture and dirt particles collect on the surface and adhere.
(A contact angle of max. 95° leads to flat water drops.)
 

With LotuTec
 
Just like in a lotus flower, the drops simply pearl off. Dirt and finger prints can be easily removed from the smooth surface.
(Contact angles more than 110° lead to ball-like water drops.)
