Focus Tunable Lenses for LED Lighting by Optotune AG

Focus tunable lenses open up new possibilities in the design of LED based luminaires. With these shape changing lenses, the beam angle of a spotlight can be flexibly adjusted while keeping the efficiency on a constant, high level. Compact solutions combining a floodlight and a spotlight in one product can therefore be realized. This innovative technology reduces complexity and offers more flexibility in lighting
design, especially for changing environments like museums, and shops. Joerg Wertli from Optotune AG demonstrates a very interesting technology for these applications.
