“Tutorial on aspheric optics”
Dr. Ulrike Fuchs
Head of Applications at asphericon GmbH
Celebrating the International Year of Light 2015
Aspheres are becoming more and more popular in optical design of lens systems. This trend is caused by the demand to reduce size and
weight or even novel optical performance, which cannot be obtained with spherical designs only. This demand lead to innovative manufacturing
processes for serial production of aspheric surfaces of high quality. However, due to the type of surface form deviation introduced
by CNC based grinding and polishing processes, tolerancing an optical system with aspheric surfaces becomes very challenging.
Especially for serial production one should avoid over-specification since this is a critical price booster. This talk will discuss how aspheres can be
employed meaningful in optical design and how tolerances have to be determined with. Special attention will be paid to surface form
deviation and slope errors, which are unique to aspheric surfaces.
Ulrike Fuchs studied physics at the Friedrich-Schiller University in Jena, majoring in optics in 2004.
Her diploma thesis addressed ultrashort pulse propagation in complex optical system and optical design.
Subsequently, she pursued her PhD in physics with a scholarship of the German National Academic Foundation at Fraunhofer IOF in Jena and received her doctor‘s degree in 2009.
Postdoctoral, Ulrike Fuchs worked as research associate at Fraunhofer IOF at the micro-optical department and as assistant lecturer at the Abbe School of Photonics.
In 2010 she joined asphericon as optical designer and became head of department in 2012. Ulrikes current position includes all research
and development activities as well as optical design with respect to the available manufacturing processes and vice versa.
