The market for high‐brightness Light Emitting Diodes (LED) is expected to grow strongly in the near future. In order to meet the rising demand, suppliers are developing new ways of manufacturing components on a larger scale. SCHOTT has now patented a precision molding process for producing strips and arrays of mini lenses made of highly refractive glass. Multiple LEDs can thus be positioned side by side and very closely together to allow for a strong and defined light beam to be formed. The precisely shaped lenses enable compact designs of light sources as well as optical systems.
