11th - High Level Expert Meeting (HLEM 2021) - 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 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.

Save the NEW DATE for our 12th HLEM 2022, March 15-17, 2022!

HLEM in Spring 2021

Our upcoming 11th HLEM 2021 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.

Five different samples are available for measurements through kind support of Berliner Glas (Berlin), Physikalisch-Technische Bundesanstalt (Braunschweig), LT-Ultra (Herdwangen-Schönach) and Asphericon GmbH (Jena). The marks on the glass samples were realized by NTG GmbH (Gelnhausen).

The following five samples are available. We would appreciate, if you could consider these lenses in your measurements:

precision cylinder (UPOB #5)

convex toroid (UPOB #6)

standard asphere (like UPOB #3) - completely made of metal (CGH for lens #3 is available)

standard asphere (UPOB #3) – unmounted (CGH for lens #3 is available)

double sided Asphere (UPOB #9) - unmounted

 

Of special Interest HLEM 2021 - ONLINE only

Our 11th HLEM will take place ONLINE only!

But despite this new format, it will again be a very interesting meeting of experts from all over the world!

Due to the new ONLINE format, the popular industrial exhibition and the poster sessions of the young scientists are held in separate virtuell adjoining rooms ...

As you can see, the topic asphere metrology remains very interesting!

Planned Main Topics of HLEM 2021

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

Main Topic:

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

Manufacturing and measurement of metal optics

Measurement of unmounted aspheres

Inner centration of aspheres

UP-Manufacturing processes

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

YSA 2021 - Young Scientist Award 

Awarding the 3rd Young Scientist Award 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 third time in 2021. 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 30.01.2021 (extended) 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
