9th High Level Expert Meeting - Asphere Metrology on Joint Investigations

In previous High-Level Expert Meetings (HLEM) and workshops, developers, manufacturers and users have confirmed the great interest in asphere metrology.

Both the introduced measurement systems as well as the results of round robin comparison 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.

Our upcoming 9th HLEM 2018 is dedicated to the presentation of measurement results of current lenses, 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.

Seven different samples are available for measurements through friendly support of Asphericon GmbH (Jena), Berliner Glas (Berlin), IOM (Leipzig) and Physikalisch-Technische Bundesanstalt (Braunschweig). We do not want to require the participants to measure the large number of samples in one run. In order to carry out a well-founded comparison, we would appreciate, if you could consider the following three lenses in your measurements:

  • small asphere (UPOB #2)
  • standard asphere (UPOB #3)
  • cylinder (UPOB #4)

Due to the demand of the participants a CGH for lens #3 (standard asphere) is avaliable!

Planned Main Topics of HLEM 2018

Several (14) companys and institutions performed measurements on the avaliable samples.
Main topic of the conference will be the presentation of the results of the newly produced seven samples.
In addition to presentation on measurements also following topics of interest are:

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

■ Measurements of small precision optics (as used for endoscopy, mobiles, sensors …)

■ In situ-measurements in complex UP processing lines for aspherical or freeform surfaces

■ Clamping technologies for measurements in aspherical lens production

■ Standardization in the description of aspheres and freeform surfaces

■ Measurements of aspherical surfaces of moulding tools for glass and plastic lenses

■ The influence of coatings on the measurement of aspheric and freeform lenses

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

9th High Level Expert Meeting - Asphere Metrology on Joint Investigations YSA 2018 - Young Scientist Award 


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 first time in 2018. 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 three best works are selected and priced.

Submissible topics are scientific papers from the following areas:

  • precision methods e.g. MRF, SPDT, IBF ...
  • approaches to additive precise optics production
  • cleaning and coating, multi-layer coatings
  • measurement technology and data analysis in the 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 15.01.2018 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 Programme.
