On 27 + 28 April 2021, the innovative high-tech fair will take place in the optical stronghold of Wetzlar for the 9th time. With a new date! Many experts look forward to the personal meeting on site - accordingly, the event is already well booked. Currently, only 15 stands are still available for booking. In order to be able to guarantee your safety in 2021 as well, we are moving the 7.5 m² stands apart. This creates more distance, but the same possibility to communicate. Places will be allocated according to bookings received. To the hall plan.
