description

The nanostractures come also to the lighting industry - they are suitable for use in almost all indoor lighting applications, but also in the case of street luminaires. Thanks to these small elements we are able to control more precise the light and achieve a greater optical efficiency. The new "flat lens" which we are working on currently are suitable for modifications of the beam angle of spotlights thanks to using the holograms. Holographic lens are just starting and we are discovering all possibilities of their usage.
