10th HLEM 2019 - High Level Expert Meeting Asphere Metrology on Joint Investigations

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. Particularly 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 2018, HLEM 2017; Workshop 2016; HLEM 2015; HLEM 2013; Workshop 2012; HLEM 2012, HLEM 2010)

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 10th HLEM 2019 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.

Four different samples are available for measurements through kind support of Asphericon GmbH (Jena), Berliner Glas (Berlin), IOM (Leipzig) and Physikalisch-Technische Bundesanstalt (Braunschweig). The new marks on the samples were realized by NTG GmbH (Gelnhausen).

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

• standard asphere (UPOB #3) - new - with marker
• precision cylinder (UPOB #5)
• convex toroid (UPOB #6) - new - with marker
• wild freeform (UPOB #7)

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

Planned Main Topics of HLEM 2019

 

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 four samples.
In addition to presentation on measurements also following topics of interest are:

Main Topic:

■ Presentation of the results of the round robin

Additional Topis:

■ The effect of marks on the sample

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

■ Clamping technologies for measurements in aspherical lens production

■ Standardization in the description of aspheres and free-form surfaces

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

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

■ The influence of coatings on the measurement of aspheric and free-form lenses

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

  YSA 2019 - Young Scientist Award 

Awarding the 2nd 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 second time in 2019. 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 15.01.2019 (extended to) 28.01.2019 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
