Optical illusion with practical effect
Would you have though that laser lamella can provide shade? No? It is difficult to imagine but basically absolutely possible.
The magic word is laser lamella. The process works just like subsurface engraving or subsurface structuring in glass.
The laser beam melts the glass inside at a point. This method can be used to introduce horizontal lamella into a glass sheet or glass elements for a curtained façade.
If direct sunlight shines on the lamella, it is reflected and dispersed.
The effect is diffuse and dispersed sunlight in the room also called "light guiding".
In this manner, laser lamella can also be used in a way to provide shade for homes.
