LotuTec® coating

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.

The advantages
  • Dirt, grease and water repelling pearl-off effect.
  • Simplified, streak-free and gentle cleaning.
  • Contrast-rich and brilliant image.
Without LotuTec
A contact angle of max. 95° leads to flat water drops.

Without LotuTec®
As with most leaves, moisture and dirt particles
collect on the surface and adhere.
With LotuTec
Contact angles more than 110° lead to ball-like 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.
