13^th - High Level Expert Meeting (HLEM 2023) - Asphere Metrology

In the field of asphere metrology, many new advancements were achieved, new measurement procedures were developed and precision was noticeably improved. In previous High-Level Expert Meetings (HLEM) and workshops, developers, manufacturers and users have confirmed the great interest in asphere metrology.

Please learn more about previous events by following links (HLEM 2022, HLEM 2021, HLEM 2019, HLEM 2018, HLEM 2017; Workshop 2016; HLEM 2015; HLEM 2013; Workshop 2012; HLEM 2012, HLEM 2010)

In order to manufacture ultra-precise and high-tech optical components and to be capable of further miniaturization, reliable and extremely precise measurement technology is required. Both the introduced measurement systems as well as the results of round robin measurements show the enormous potential of this field of technology. In addition, a great need for comparability, standardization and proximity to users was also pointed out.

ONE Location TWO Events

In spring 2023 a special event will take place - a combination of scientific event and trade fair. On the one hand our popular HLEM takes place, on the other hand, the intersting W3+ FAIR Wetzlar is held at the same time.

For the first time the Competence Centre Ultraprecise Surface Processing UPOB is taking advantage of the trade shows top class environment to host the 13^th High Level Expert Meeting (HLEM 2023). The two day event with topic Asphere Metrology kicks off the day the fair is set up, March 28^th 2023.

The cross-industry platform (W3+ FAIR) for enabling technologies, invites companies from optics, photonics, electronics and mechanics to Buderus-Arena Wetzlar.

HLEM in Spring 2023

Our upcoming 13^th HLEM 2023 is dedicated to the presentation of measurement results of current lenses (5 parts), discussion and dissemination of new developments and recent scientific results in asphere and free form metrology for reflective and transmissive surfaces. With this broader scope we aim to supplement our previous events while also addressing asphere and free form metrology to interested scientists, developers and manufacturers.

The five different samples are available for measurements through kind support of Asphericon, Leica Camera, Innolite and Edmund Optics. The marks on the glass samples were realized by NTG.

The following samples are available:

■ asphere steep 15 mm (#2.1) - mounted on mandrel

■ double-sided asphere concave 28 mm (#10.1)  - unmounted

■ asphere metal mould insert 4,6 mm (#11.1)

■ asphere lens 10 mm (#12.1) - unmounted

■ double sided asphere convex 25 mm (#13.1) - unmounted

Planned Main Topics of HLEM 2023

Several companys and institutions are planning to perform measurements on the available samples.
Main topic of the conference will be the presentation of the measurement results of the four samples.

Main Topic:

■ Measurement of small lenses

■ Presentation of the results of the round robin

■ Comparison of current results

The following topics are also of interest:

Additional Topics:

■ New developments in measuring techniques for aspherical, free-form and cylindrical lenses

■ Measurement of unmounted aspheres

■ Measurement of endoscope optics

■ Measurement of mobile phone optics

■ Inner centration of aspheres

■ Other topics related to asphere and free-form metrology or production

YSA 2023 - Young Scientist Award 

Awarding the 5th Young Scientist Award will round out the programme!

In addition to the scientific part of the event, which focuses on the topic of asphere metrology, the CC UPOB e.V. will award a prize for the 5th time in 2023. Young scientists up to the age of 30, have opportunity to present their work to an interested specialist audience during the High-Level Expert Meeting. By a jury of the participants the best work will be selected and priced.

Submissible topics are scientific papers from the following fields of activity:

■ precision methods e.g. MRF, SPDT, IBF ...

■ approaches to additive precise optics production

■ cleaning and coating, multi-layer coatings

■ metrology and data analysis in production chain for aspheres and freeforms

■ ultra-flatness; diffraction base plates; nanostructures

Applicants have the opportunity to apply with an abstract in english with a picture and 250 words by 15.01.2023 ==> extended to 22.02.2023 at the CC UPOB e.V. office.

At the beginning of the conference, the pre-selected works will be presented by the candidates in a short presentation.
During the breaks, the participants can continue to find out about the topics in a poster session.
At the end of the conference, the award ceremony will take place.

You will find more details in HLEM Call for Papers and also in HLEM Program Flyer.
