13th High Level Expert Meeting

28 + 29 March BUDERUS ARENA | Conference Room 2.OG
Start: 11.30 AM | Conference on 28 March: 12.30 – 5.00 PM | On 29 March: 8.30 AM – 12.30 PM

In the field of aspheric metrology, many new advances have been made, new measurement methods developed and precision significantly improved. In previous High-Level Expert Meetings (HLEM) and workshops, developers, manufacturers and users have confirmed the great interest in aspheric metrology.

In order to be able to manufacture and further miniaturise ultra-precise and high-tech optical components, reliable and extremely precise measurement technology is required. Both the measurement systems presented and the results of interlaboratory tests show the enormous potential of this field of technology.

There is a fee for participation!
The meeting will be held in English.

IVAM Expert Group Meeting Photonics

29 March

As a key technology of digitalisation, photonics is becoming increasingly important in the high-tech industry. Photonic sensors, such as cameras or radar systems for optical distance and speed measurement, have become an integral part of everyday life.

The vehicle and supplier industry is undergoing a fundamental transformation. To accompany the transformation, many partners have come together in Central Hesse to build a regional transformation strategy and a network for the vehicle and supplier industry. The “TeamMit” project – funded by the Federal Ministry of Economics and Climate Protection – was launched at the end of 2022 to achieve this goal. To this end, suitable offers are being developed in the areas of research & technology and further education & qualification as well as promotion.

The future of the automotive industry is inconceivable without innovations from optics, electronics and mechanics. For this reason, the project team would like to bring the industries together in a joint tour.

The tour is aimed at: People from companies, higher education and training institutions as well as institutions that are active in the automotive industry or would like to become active.
