Micro-lens for mobile phone flash light (Heptagon, Finland)

The micro-structured lens consists of a mixture of refractive and total-internal reflection structures arranged in a sectored way in order to perform the beam shaping of an optical beam emitted by an LED.

The combination of both types of structures allows to have superior performances in terms of efficiency (and uniformity, to ensure an optimum illumination.

The use of the new hybrid micro replication process enabled the production of this demonstrator with superior performance.
